Let's show off pieces of our collections, with a twist: Every person who posts a piece posts one that is 1 geologic time period younger than the last. Example: If a Jurassic crustacean is posted, the next post needs to be something from the Cretaceous, and so on. Starting from the Cambrian going all the way to the Pleistocene (Cenezoic time periods will be divided into the epochs, since they're more commonly referenced), and looping back to the Cambrian after someone posts something from the Pleistocene. Let's see how long we can keep the descending order going! I'll start with a Barrandagnostus inexpectens agnostid plate with other trilo-bits on a Cambrian shale slab from the Conasauga Formation:

Alright fossil preppers, show us what you're working on! I've been working on prepping this Priscacara for about 6 months on and off with a pin vice.

Show us your tyrannosaur fossils! My only tyrannosaur fossil is a small fragment of a tooth, but it has some really cool patterns. I can't post pictures right now but will later. So show us your fossils!

If there's one thing that really makes me gasp, it's cartilage. Especially a whole darn skeleton (a shark, sturgeon, paddlefish, anything with a skeleton composed largely of cartilage.....) I find cartilage to be so amazing because of how difficult it is to be preserved. Plus, I find anything fossilized with cartilage also maintains other minute details (sensory pores, skin pigment, really fine details.) this is is a thread for anybody who wants to share their cartilage! I just realized the irony here, my name is Bone guy.....Anywho here is my contribution. A paddlefish named Protosephurus liui from the Early Cretaceous shale of the Yixian Formation (same place they found the Yutyrannus) in China. These fish are very cool, they do have a good amount of bones in their skeleton but there's also lots of cartilage. Hairs lined along the rostrum can sense the tiniest bit of underwater disturbance. You can see the skin is covered in tiny dimples which are sensory pores. Overall this animal is armed with a high tech radar system, perfect for hunting the smallest of invertebrates.

We've all seen riker mounts, and glass cases, so show us you're weirdest display!
