Henry held your hand tight as you guided him to the elevator.

JJ had just gotten back from a trip to Michigan for a case. She ended up sleeping for a couple hours before she had to go back into work again, all before little Henry woke up for the day. Since she hadn’t seen her son in almost three weeks, you thought it would be nice to bring Henry to her with some lunch as a surprise.

You had been JJ and Will’s nanny for almost 8 months now. Since Will had returned to work and JJ’s job was still incredibly demanding, they started looking for a nanny for their 3-year-old son. You just so happened to be looking for a job and to finally put your experience as a nursery assistant back home to good use. 

“You excited to see mummy?” You asked Henry as you stood in the elevator, his little FBI visitor badge far too big on his little body.

“Yeah!” He replied excitedly, jumping up and down while still holding your hand. You had taken Henry to pick up some lunch at JJ’s favourite place then let Henry pick out a pastry for each of you to have for dessert.

“Alright, remember, you have to hold on tight to my hand, okay? There are lots of people around,” you reminded the young boy, crouching down to his level.

“Uh huh,” Henry nodded, his tiny hand squeezing yours.

The elevator dinged and you gently guided Henry toward the bullpen, silently searching for JJ’s office. Henry stayed close to you as you swerved through the busy agents. You decided to ask someone who you thought looked vaguely familiar.

“Uh, Emily, right?” You gestured toward the dark haired woman sitting at her desk.

She glanced up at you, seeming to recognise you and little Henry almost instantly, “Oh hey! You’re Y/N, right?”

“Yeah, I was just wondering if you could point me in the direction of JJ’s office-”

“Did you know the Australian mainland extends from west to east for nearly 2,500 miles?” someone behind you said, obviously hearing your Australian accent.

Emily rolled her eyes and looked at you, “don’t mind, Reid.”

You turned around to look at ‘Reid’, he was cute, probably the young doctor JJ told you about. You pointed at him, “Dr. Spencer Reid, right?”

He ignored you, “And most of the rocks forming the foundation of Australia are from the Precambrian and Paleozoic time… about 4.6 billion and 252 million years ago respectively,” he looked up at you, “yes, I’m Dr. Reid.”

“Mm,” you hummed.

“I’ll go get JJ for you,” Emily sighed, frowning disapprovingly at Reid. You sat down next to Emily’s desk, picking up Henry to sit him in your lap.

“Where are you from?” Another man asked, “I’m Derek Morgan, you must be Henry’s nanny?”

“Yeah, I am… I’m from Melbourne,” you smiled.

Spencer interjected, “Melbourne isn’t said like that. The spelling negates that.”

“Kid… she’s from there, I think she knows how it’s said,” Morgan retorted. 

You just chuckled softly, “I’d love to hear you mansplain my country to me, Dr. Reid.”

“I’m not mansplaining,” Spencer replied, seeming offended.

“You kind of are,” Morgan added, leaning back in his chair.

“Mansplaining!” Henry exclaimed, making both you and Morgan laugh. Henry bolted from your lap the moment he saw his mum. You stood up to greet JJ as little Henry tackled her in a hug.

“What are you guys doing here?” JJ asked, cuddling Henry close to her.

“We thought we would surprise you for lunch,” you smiled, “Henry picked some pastries out for us too, for dessert… I hope it’s okay?”

“No, it’s perfect,” JJ replied, “it’s just what I needed honestly,” she sighed, giving you a side hug as she guided you to her office.

Henry sat on the floor playing with a few toys you brought along for him while you and JJ talked, “so, that Dr. Reid? He’s a character.”

“You met him, huh?” she leans back in her chair with a laugh.

“Oh yeah,” you replied, “he seems…” you trailed off.

JJ nodded knowingly, “Yeah, he’s like that.”

“He’s cute though,” you shrugged with a small laugh.

“Mm, I’ll make sure to tell him that,” JJ teased.

“Don’t you dare,” you retorted quickly. 

You spent the last half an hour of JJ’s break sitting with her and Henry on the floor helping him do a puzzle he had left from the last time he was here. It was nice for JJ to see her son, she missed him terribly but she knew he was in good hands with you.

JJ had to get back to work shortly after and she squeezed Henry in a tight hug, reminding you she might be late again tonight, which you didn’t mind. 

“Say ‘bye-bye’, mummy!” You held Henry’s hand, waving at JJ. 

“Bye-bye, mommy!” Henry called, waving his little hand around. 

You spun around, guiding Henry through the bullpen again before an idea popped into your head. You turned on your heel at the side of Spencer’s desk.

“Hey, Dr. Reid?” You asked softly.

“Yes?” He peered up at you.

“Ever heard of drop bears?”

a/n: i hope you liked it! i know it was a short one but i think it's funny. another chapter of pierced coming soon >:)

how long have you been on tumblr and why havent you moved on to twitter or whatever?

When the first sunlight hit the galactic debris that had not yet become earth, no one asked why. It just fell together, the inexorable pull of gravity drawing momentum into orbit, all things great and small finding balance or destruction in billion-year ballet, colliding and combining into the only fragment of rock and water we know to contain life. In the shallow seas of the Precambrian Era, no one asked how long; they simply swam in the endless dreaming of being in its most rudimentary form. And when Chicxulub turned the skies white with fire and flung the oceans up shores the world over, burned forests with only the heat of its impact and showed Tyrannosaur the true meaning of thunder--nothing asked the Cretaceous if it was ready to be done. It just was. And nothing remembers how or why, we can only reconstruct from the echo left behind.

Someday, dear anon, this blog will post no more, and someday no one will know it was here except for whatever echo lingers in the electric memory of the internet. And when that day comes to pass, when this strange corner of the hellsite falls silent--well, maybe the echo will tell you what became of me.

I've been here for twelve years. I assume at this point it would take a cataclysmic meteor to take me out.

#technically speaking i do have a twitter #i just literally never use it for anything #i lurked on this site for a couple years before I actually made a blog #I've been here a long damn time and I'm too lazy to try and establish a following somewhere else #also twitter is a cesspit thank you very much

A little lump of carbon falls to earth in the precambrian.

I imagine that fungus came to earth as a meteorite, and landed in a microbial mat that they decided to take up as a body. If you peeled back all the layers of goop and slime that they're made up of, you'd be able to find a little ball of rock floating around inside of them. The rock isn't their body anymore and it isn't a "core" to their being whose survival depends on it being there, but they're a sentimental person and believe that it's important to remember where they came from.

Surface Geology vs Radiation

by u/aspenmoniker

I recently acquired a gamma ray scintillometer that has a really neat mapping function. So as an exploration geologist, it has really added new depth to enjoying and understanding the local geology when I am out and about on hikes. In the particular image above, you can see that this instrument measured more CPS in Tertiary tuffaceous sandstones than in Precambrian basement rocks. This could have a number of applications for trying to map complex surface geologic terranes, or perhaps trying to tie surface outcrop data to subsurface logs.

I am sitting down on the number block carpet I want to hear about him

Bob is an eldritch monster (I've just been calling their species Worldeaters, I don't have any plans to change the name) that eats planets and rocks in general (Stars too but that's a rare snack).

He was laid on Earth sometime during the end of Precambrian Era. And hatched a year BEFORE the Cambrian Era officially started. His parents kind of just left him there (due to their species they can't exactly stay with him, they do visit sometimes though!) with a babysitter so he wont be completely alone growing up.

Bob's just kind of vibing on Earth until he reaches maturity :)

#So yeah. Age wise he's a bit younger than the earth #So at least 3.7 eons old :) #<- that's the age of the oldest known fossils #The earth is estimated to be 4.54 eons old #In Worldeater terms he's still an infant. It's going to be long ways away until he's an adult #I feel like he matures mentally a lot during this time? While he's actively awake and learning I mean #Like his brain's still mushy and s mo o t h since well- not fully developed but he can understand concepts like language and stuff #But he's still in no way an adult. #He'd pretty much sleep until he gets hungry again for the first few centuries of his life cause there's not anything 'fun' happening #So when life starts to develop on land and animals start to move onto the shores he stays awake a lot more often because 'ooo new friends!' #And by the time of the dinosaurs-modern day he is MUCH more awake and actively interacting with the things around him #Bob's lore forced me to do so much research into the earth and space my god. #Kos speaks #[Bob Beloved]

Another thing I quite like is that while there are elements of Demon King!Ganondorf that are clearly meant to evoke Demise, upon closer inspection Ganon’s not a 1:1 copy of Demise. In fact, his elemental affiliations are very different from Demise.

For example, the “ruffles” on Ganondorf’s robes are meant to evoke Demise’s scales, but they’re not actually real scales. They’re just the fabric of his robe torn up and glowing after being soaked in Gloom. His actual physical markers that denote both his inhumanity and the nature of his powers are underneath the clothing, on his skin; these peekaboo openings of see-through flesh on his chest showing the Gloom pulsating and churning within him, like his body’s a transparent glass vessel storing the stuff. He looks sodden and wet with Gloom, and his hair moves like he’s eternally underwater.

Demise’s hair is either made of fire or meant to evoke fire with the limited graphical capabilities the Wii possessed. Ganon’s hair, while evoking flame by being red and glowing, isn’t actually on fire. He’s actually got these prehensile tentacles of “hair,” and if you look closely you can see the Gloom pumping through each tendril to move it around like a hydraulic pipe. I also noticed that when Rauru stops Ganon’s heart, his hair stops moving and his body stops glowing, implying that what’s making the Demon King light up is not some “inner fire” but his own lifeblood, pumped through his veins and allowed to seep out of his body by his own heart.

So even though they’re visually similar, elementally the two kings are actually opposites. While Demise is fire and volcanic rock and “superheated things erupting from the earth,” Ganondorf is more like water, blood, maybe some associations with the sea and tides through his affinity for the moon. If Demise’s Upheaval was like a volcanic eruption forcing lava through the earth, then Ganon’s Upheaval was more like a geyser of ultrapressurized and superheated groundwater finally breaking through the layers of rock it was trapped under. If Demise was like the chaos at the beginning of the world when the earth was still a lifeless ball of molten rock, then Ganondorf was like what came after—the rain and the primordial sea, the precambrian explosion of life in the monsters called up by the sacrificial spilling of his own blood, the ancient nonvascular plants and giant fungi of his realm/prison in the Depths that had long since gone extinct on the surface. And after his escape, his Gloom spatters around the depths like a trail of bloodstains leaking from his death-wounds.

They’re superficially similar, but in reality they couldn’t be more different. I think that’s really neat.

I just want to look at rocks, not calculate the reaction rate of chemical stuffs

Like bam!!! Look at the rock! So much easier

(Funfact this is Precambrian in age! It’s made up of K-feldspar (pink stuff) and hornblende (black stuff)

In 1957, schoolboy Roger Mason and his friends were rock climbing in Charnwood Forest in central England where they stumbled across a strange leaf-like pattern embedded in the rocks. The unusual fossil was brought to the attention of local geologist Trevor Ford, who published the discovery in the Journal of the Yorkshire Geological Society. This fossil is particularly fascinating as the rock layers in the area are known to be Precambrian in age. A time previously thought to be prior to the appearance of complex life.

Charnia (named after the Charnwood Forest in which it was discovered) was an unusual frond-like lifeform from the late Ediacaran period, 570-550 Mya. It had segmented leaf-like ridges branching out from the center asymmetrically, indicating it likely evolved before bilateral symmetry, a feature present in nearly every living thing today. Specimens have been found ranging anywhere from 1cm to 66cm in length. It lived on the sea floor feeding on nutrients in the water, and despite its plant-like appearance, the nature of the fossil beds it was discovered in indicates it lived too deep to effectively photosynthesize like plants do. Instead, our current understanding of the lifeform places it as an early member of the animal kingdom.

Charnia is a significant discovery as it is the first Precambrian fossil to be identified as such, completely changing our understanding of how life came to be. So little is currently known about Ediacaran biota that we don't know how or even if these creatures are related to life today.

Fossil Friday: Echinoderms!

Echinoderms belong to the phylum Echinodermata and are usually recognized by their radial or pentamerous symmetry.

This group includes starfish, brittle stars,

sea urchins, sand dollars,

sea cucumbers, sea lilies, and a number of extinct genera.

They are found at every ocean depth on the sea floor and are the largest marine-only phylum.

Echinoderms have both ecologic and geologic significance. There are few other groupings so abundant on the deep sea abyssal plains as well as the shallower shelf environments. Most can reproduce asexually when needed and they can regenerate tissues, organs and limbs.

Geologically, their ossified skeletons can provide clues to the paleoenvironment and they are a major contributor to limestone creation and deposition.

The first definitive echinoderms evolved in the earl Cambrian Period during the Cambrian Explosion (with one possibly older than that if it is indeed, an echinoderm). The name echinoderm means "hedgehog skin" in Greek. There are 7,000 extant (living) species and around 13,000 extinct ones. But what did those earliest echinoderms look like? The answer is : not much like modern ones. Shocker, I know.

The oldest possible echinoderm, Arkarua, came from Edicaran-aged rocks (end Precambrian Era) in Australia. It was a small, disk-like fossil with a raised center, radial ridges along the rim and a five-pointed central depression marked with radial lines of five small dots. They ranged from 3-10 mm. Tiny little guys.

Cambrian echinoderms were a little less obvious, more like weird pedicure heel scrubbers. One did look a bit like an early crinoid, and the one in the corner looks a bit like a taser.

In younger rocks, you'll find things like cystoids, blastoids and crinoids and eventually starfish and other recognizable echinoderms.

How do you think evolution exists in the Cars universe. Axelrod in 2 says they are using fossil fuels, so does that mean at one point there were single cell cars???

This is interesting! Fossil fuels like oil and coal are usually formed from plant matter and smaller organisms mostly, but for the sake of this ask I’ll focus on oil formation. We know that organic matter like plant life is commonplace in the cars world, and we also know that there where pre-historic dinosaur cars that later evolved into the cars we have now. These dinosaurs were made mostly of metal and rock so it isn’t crazy to imagine that their joints and other organs were organic matter than could be broken down into these fossil fuels over millions of years.

Seen here:

We can see they have tongues and that’s enough proof for me that they have other organic parts (also I love how their snouts are shaped like the main body of the car so you can see how they evolved and stuff that’s fun)

Anyway! Back to the main point of your question, what was the starting point in the evolutionary process? Did cars evolve from single celled organisms? Maybe! It would make sense, and this leads to my personal belief that in the first few eons on earth during the Precambrian era single celled organisms evolved to use things like metal and rock as an exoskeleton of sorts, and once they got further down the evolutionary line it just sort of became part of them.

This is all very loosely based lol because if you think about it for too long it starts to become increasingly difficult to explain lmao. But yeah this is the jist of what I think!
