Neat paper out today by Jin-bo Hou, Nigel Hughes, and my former postdoc advisor Melanie Hopkins detailing structures showing how trilobites could clean their gills!

Figuring out how ancient creatures lived and moved is always awesome.

The Scottish Silurian eurypterid Slimonia for #FossilFriday!

This specimen is a molt and shows the head shield which has been displaced from the appendages underneath. They include the chelicera (marked in green), pedipalp (blue), walking legs (orange) and paddle (red)!

As I recover from my wisdom tooth extraction on #FossilFriday, I was reminded of this amazing fossil shark from Peru in the collections of @FloridaMuseum. I don't know why.

Found this on the title slide of an old talk while I was trying to cannibalise a bunch of talks for a talk I can give tomorrow.

I have no idea where I found it, but I wanted to share it! If anyone knows who did it let me know and I'll share that, too.

This new #Cambrian critter is fascinating; related to the predator Anomalocaris and filter-feeder Aegirocassis but living like neither, it seems to be a mud-grubbing sweep-feeder, like some of the eurypterids that evolved later in the Paleozoic. #fossils
