Neozoic sharks by JWArtwork Neozoic sharks by JWArtwork
Batocanthus rajiformis and Pachycephalocanthus anguiliscus are two species of Neozoic shark. They both live some 127 million years from now (Early-Palalom) in the waters around Australia. Batocanthus is a bottom-dwelling shark that has replaced rays. It's relatives can be found on every continent in both fresh as well as marine waters. This has caused the vast majority of the rays which were still left after a big extinction, to vanish. The pachycephalocanthids also know global distribution, and although they can live in fresh or brakish water, the prefer a marine habitat.

In fact the pachycephalocanthids (eel-sharks), descendants of the fox-shark, use their massive heads, not only to fight off predators, but also to bump in on ray-sharks which live at the seabed. This way the prey is weakened or even paralised and can be easily hunted down. Just like the mammal-shark it has enlarged backfins to make it look more impressive. The tail of the shark is also different from what we see in modern sharks. In fact the fox shark has a small flap of skin under the end-part of the tail. To swim more efficiently in its eel-like way, the eel-shark has evolved another tail fin out of this little flap. [link] It is incredibly efficient and grants the shark a fast attack and also a greater chance to outswim potential predators. Its length varies from 2.5 - 3.5 meters.

The ray-sharks (also named butterfly-sharks or dragon-sharks) are descendants of the bull-shark and have a similar lifestyle to rays, although they sometimes also swim up to the higher waters to hunt. Its maximum length is 1.5 meters.

Again I was not in favor of sharks, when it comes to the future. Both sharks will be a good lunch for a hungry Muraeonctinus! ;) [link]

I like the design of Bathocanthus, and the body form of the eel shark reminds me to Crassigyrinus. Good work :)

Thanks a lot! I'm glad you like it! :bow:

Yes, Crassigyrinus, now you actually mention it. To be honest, I was actually inspired by Xenacanthus, Hybodus and the frilled sharks. ;)
