By studying calcifying organisms, Leanne aims to better understand the impacts of human activity on marine ecosystems. Through her research, she hopes to influence policy that helps protect marine calcifiers in the future.
“Why is this important? The idea is that the more porous the shell, the weaker it is. Mussels need strong, robust shells to protect their inner soft organs—and that strong 3D structure is important for ecosystem function as habitat formers and storm defenses.
Currently, the changes seen in shell porosity are not large enough to influence the material properties, so we aren’t seeing weaker shells just yet. But with further warming in our oceans being predicted, this could potentially lead to even more porous shells, potentially impacting mussels’ function as habitat formers and storm defenses, as well as their ability to protect themselves from predation,” Melbourne explains.
gf and I were lamenting the lack of exhibitions about dinosaurs that had updated accurate depictions when we happened upon This Beast. NY’s American Museum of Natural History, T. rex exhibit from 2019. We’re losing our minds over the fact it just has a head of hair and no other feathers. Thoughts?? Insight???
Better than nothing, depressingly low effort tho
esp given AMNH had the "Birds are Dinosaurs" exhibit not long before that and it was one of the best things I've ever seen
It's time for Fossil Friday! Meet Cryptocleidus oxoniensis, a short-necked plesiosaur. Plesiosaurs were large marine reptiles that lived from the late Triassic to the end of the Cretaceous. The plesiosaurs had extensive modifications to the shoulder and pelvic girdles: these elements form large, flat sheets of bone, presumably for the attachment of swimming muscles. Cryptocleidus' trunk was very rigid and short, and the short tail could only function as a rudder, leaving the limbs as its main organ of propulsion.

Went to the Van Cleef & Arpels emeralds exhibit at the American Museum of Natural History. It’s in the diamond room in the hall of gems. Incredible pieces
