Pterosaur Heresies posts about sharks are my favorites, because it's clear that he's just pulling images off the internet without reading any scientific literature. For reference, these are actually both juvenile basking sharks of similar length and not "an adult and juvenile".

@udurawane @megalotitan Can confirm, hyoliths are Mammoth Cones.

You may have heard of the Mammoth Cube, but have you ever heard of the Mammoth Spiral? This is Elephantoceras spinodosum, a goniatite ammonoid with large tusk-like projections on its shell.

@Death2Britain Some mantis shrimps have clubs that they use to stun/kill prey.

@tmkeesey @BrianEngh_Art @WilliamBabey @Yara_Haridy Edward Hitchcock had an even earlier tree from 1840, possibly the earliest. It's also more organic looking than our modern trees.

I still can't get over this Eocene frog.

The next entry in my "Reconstructing fossil cephalopods" series is here, this time on Enchoteuthis (the cephalopod formerly known as Tusoteuthis). Again @Prehistorica_CM kindly provided the artwork.

@BritishPalaeon1 Pretty plausible based on the hyoids from Pinacosaurus.

Someday I'll get around to that post on high-finned sperm whales, and how they're the result of mistranslations, misidentifications, and overall taxonomic confusion.
