Spinosaurus drama is cool and things, but do you know what's even cooler? Better fossils of animals that lived with Spinosaurus!

There is a new specimen of Concavotectum currently on display in Tuscon. BigSkyFossils took some photos of it and I had to doodle it! It's been a while since I did a tselfatiform and now we have finally an idea how the postcranium looked like!

So far we only had a few fragments and this pretty good skull. As some people noted though, the eye is reconstructed in the wrong corner.

Happy Fossil Friday!

Who: Coelacanthiformes

What: Coelacanths! Large lobe-finned fish from the Class Actinistia, a close relative of the lungfish.

When (group): Devonian - Present (thought to have gone extinct during the End-Cretaceous extinction event, but members of the group were "rediscovered" in 1938)

Where: (Living representatives) along the east African coast and the Comoros Archipelago in the Indian Ocean.

(Fossil representatives) England, Czech Republic, France, Germany, India, Switzerland, Brazil, Democratic Republic of the Congo, China, Uruguay, USA, and more.

Fun Fact!: There are two living speices (that we know of) of Coelacanth: Latimeria chalumnae & Latimeria menadoensis

Here is a link to an article for the story of how this "living-fossil" was rediscovered by the scientific community and the museum curator who's quick thinking and determination helped bring this animal back into the spotlight.

Why are they cool?: Instead of the bony vertebral column shared by other vertebrates the coelacanth retains the ancestral fluid filled notochord which is less rigid than vertebrae, but offers more flexibility.
