Where can I derive a dinosaur name from a toy?

Question

I bought a packet of 6 dinosaurs and two of them I don't know the name. I've been looking everywhere on the net for a list of dinosaurs & their name, but it's not easy.

The two I can't name - one looks kinda like a triceratops without the horns, the other looks like a komodo dragon, with a large sail on its back?

any ideas?

Answer 1

The hornless ceratopsian is likely Protoceratops - one of the earliest members of that group, most famous from the findings of Roy Chapman Andrews during his expedition through the Gobi desert in the 1920's.

Here's a reconstruction of Protoceratops http://www.revista.unam.mx/vol.2/num4/sabias1/imagenes/protoceratops.jpg

The other one sounds like it is probably Dimetrodon, which was not actually a dinosaur, but a Synapsid reptile (somewhat close to the lineage that eventually produced mammals), in a group called the Pelycosaurs that lived in the Permian period before the dinosaurs ever evolved. It is thought that Dimetrodon may have used the sail for thermoregulation - turning it towards the sun to heat up its body, or turning it away when it was growing too warm.

Answer 2

Latter one is Pterodon. Dunno the first
