Reposted by AmbroxKrista Koeller @kristalerista.bsky.social · 09/07/2026One of my favorite things about mammals having to have exactly 7 neck vertebrae, no more, no less, is that to make your neck a different length, you have to change the length of your vertebrae. This has gotten very silly in dolphins. 📷Tursiops truncatus: macroscopic solutions, earth. com 611837

Ambrox @ambrox.bsky.social · 05/06/2026And another one!! A Primobucco has been finished after 5 collective months of scraping! I’m so happy how this one turned out, I’m sincerely hoping I can work on more of these Green River birds in the future, given we can get ahold of any. Also pictured is a modern relative of Primobucco. 010

Ambrox @ambrox.bsky.social · 11/08/2025Megacerops was a large ungulate from the White River Formation (38-33 million years ago) of the Midwest in the US. They resembled Rhinoceros, but had bony nasal horns that were covered by skin, not a keratin horn! #paleoart #fossilart 0113

Ambrox @ambrox.bsky.social · 18/07/2025My first big bird project is done! I’m excited to show you all this bird that took me so long - at least a few months! This guy comes from the green river formation and is the most common bird found there: Primobucco mcgrewi. 13912
Ambrox @ambrox.bsky.social · 14/07/2025Here are the answers to today’s #findthefossil! Some of the suspicious looking bits are actually dead sagebrush leaves. Included in the mix here are turtle bits, various dinosaur chunks, and maybe some crocodilian bone pieces. I’ll try to post some more of these challenges in the future! 150
Ambrox @ambrox.bsky.social · 13/07/2025Here’s a game for y’all!
