POV: you went diving at night and spotted Ordovician nautiloids feasting on a eurypterid carcass, after a while the commotion has attracted the giants, Endoceratids slowly creeping into view

Dawsonoceras is another cephalopod that swam the waters of Sillurian Gotland. They are an orthoceratid straight-shelled nautilid that floated in a vertical position on the water collumn.

Although they are far smaller than some of the other orthocones and endoceratids that reached lengths of up to 5 meters, their shell is just as beautiful to behold.

Kröger, B. (2013). The cephalopods of the Boda Limestone, Late Ordovician, of Dalarna, Sweden. European Journal of Taxonomy, (41).

Above specimens A,B, & E are dawsonoceratids, Scale bars: 10 mm.

From what I can gather, their adult shell diameter reaches 2.5 cm wide and it's hard to guess the total length because a lot of the shells are fragmentary. There seems to be one complete specimen online that was described to be 7.1" inches long

And another here that's 40 cm long, although it's an ID-guess from the blog poster
