Shape of the Sail with Spinosaurus
Troodon posted a topic in Fossil NewsA brief and interesting blog by Scott Hartman about the shape of the sail with Spinosaurus. https://www.skeletaldrawing.com/home/the-road-to-spinosaurus-ii-known-unknowns11252020
DinoFossilsUK posted a topic in Fossil IDI'm looking for a little help identifying this bone from the Kem Kem Beds. It looks to part of a vertebra - it's almost 6 inches long so I immediately thought that narrows it down to being a partial Spinosaurid or Charcharodontosaurus vertebra. After spending ages looking through previous post and searching for detailed pictures of vertebrae, I came to the conclusion it belongs to a Spinosaurid (Spinosaurus or Sigilmassasaurus) because the shape just looks wrong for Carch (although there isn't much to go off for Carch vertebrae). Just looking for some input as to whether I'm correct as I kn
Spinosaur tail vert and sail
BadlandTraveller posted a topic in General Fossil DiscussionJust wondering on this guy.... The sail seems to be 100% vertical which would mean it was at or very near the center of mass. Since there is only one sail vert that should sit completely vertical and the others showing a tilt I'm curious what you all thought of this specimen.

General dimetrodon/sphenacodont talk
Still_human posted a topic in General Fossil DiscussionHey everyone, this is for anything Sphenacodont--dimetrodon, or otherwise. Collections/pictures/discussions/whatever. This is the splinter thread off of the sphenacodont collections thread, so if anyone would like to bring over anything from the other thread, please feel free. I'm going to bring over some interesting posted info that covered different topics, and with links to interesting and useful info. *some discussions covering other things and animals in relation to sphenacodonts is perfectly fine. For instance, spinosaurus, Permian topics, apex predators, or whatever. As long
Still_human posted a topic in Fossil IDOk, so this is supposed to be a spinosaurus vert, one with part of the sail. At first glance it seems perfect, but upon further study, while trying to place it on spinosaurus skeletons, it doesn't seem to match any exactly. For one thing, spinosaurus sails, at least in the relatively insignificant amount of individuals on display, sail bones that don't go any higher than this one(it appears this is a fully intact sail vert), don't seem to get as wide. And the ones that do, then continue up and get thinner. There ARE similar shaped "sail" bones, at the transition to the neck, and tail, but thos
