Colors of the Dekkar Formation - Spinosaurus sp.

Here are a beautiful pair of Spinosaurus teeth! The smaller one, a juvenile, lies in-situ with the beautiful colors of the matrix

Behind is an adult Spinosaurus tooth

In my mind the adult protects the juvenile; a family 💙

The Japanese government shared a video promoting international tourism to Fukui Prefecture, which is well-known domestically for its dinosaur fossils and museum, but is not famous abroad.
They are hoping that foreign dinosaur lovers will visit.

Could any #paleoartists help me understand muscles in sitting therapods? Or muscles in therapods? I want to make an #allosaurus sculpture, but I don't quite know how the muscles work/what I need to change. Any tips, references, or more are greatly appreciated!! #dinosaur
