Ostenocaris

Ostenocaris is a Jurassic species of giant Thylacocephalan crustacean, sufficiently distinct from its relatives to be placed in its own family, Ostenocarididae. It is believed to be a bethonic animal and one of the most important necrophagus animals of his environment.[3][4]

Distribution
Fossil & Model

Ostenocaris lived during the Sinemurian age of the Lower Jurassic), and has been found in rocks at two sites in the Italian Lombardische Kieselkalk Formation. This formation is known for its good preservation, with fossils of annelids, fishes, and plants.[5]

gollark: Lisps and stuff are actually different.
gollark: Those are fairly C-like with the main difference being better memory management and some level of object orientation.
gollark: What languages are you meaning specifically? There are many not-particularly-C-like ones.
gollark: I think making a less efficient Python program (with intensive mathy things done via numpy etc. which use bindings to C) makes a lot more sense than having a possibly-faster C program which takes several times longer to write, in most cases.
gollark: It's a poor performance decision (although you can just use pypy, which doesn't have that), sure.
