BioBob Posted June 4, 2020 Share Posted June 4, 2020 I've got this long flat bone from the Kem Kem with a wide base, it was presumably attached to a larger bone. It also seems like it's missing the tip. I thought it might be a small spinosaurid neural spine but it has a weird lump of bone on one side so it seems like it is something else. Is this lump a muscle scar? Or a healed wound? And could this bone be an odd spinosaurid neural spine or is it something entirely else? Link to comment Share on other sites More sharing options...

BioBob Posted June 4, 2020 Author Share Posted June 4, 2020 I don't know of any animals that have a chevron that is so thin with a so sharply widening base. But thanks for suggesting Link to comment Share on other sites More sharing options...
caterpillar Posted June 4, 2020 Share Posted June 4, 2020 It's a half chevron https://cults3d.com/fr/modèle-3d/divers/spinosaurus-tail-section 1 http://www.paleotheque.fr Link to comment Share on other sites More sharing options...
BioBob Posted June 4, 2020 Author Share Posted June 4, 2020 It does indeed look like that! Thank you! Any idea as to what animal this belonged to? It does seem to resemble chevrons from your link and even more so the Spinosaurus neotype. https://sketchfab.com/3d-models/chv7-spinosaurus-aegyptiacus-neotype-ca70592e5d07408980220d639bc1456f So it could be spinosaurid, unless there is other Kem Kem fauna that has similar chevrons.

BioBob Posted June 4, 2020 Author Share Posted June 4, 2020 I made a quick edit to compare the bone with a Spinosaurus neotype chevron and it seems like you are right 1 Link to comment Share on other sites More sharing options...
LordTrilobite Posted June 4, 2020 Share Posted June 4, 2020 I agree. Definitely a chevron. 1 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
