    Spot the Vetulicola?

    There is a Vetulicola (partial) somewhere on this piece, I have been looking at it for awhile but I can't really spot where it is on here, anyone more familiar with Chengjiang fossils able to spot it or id for sure as vetulicola?

    Elrathia kingii

    Collected on a field trip to U-Dig Utah and prepared at the U-Dig site station. After a light mechanical brush exposed the shale, mineral oil was applied with another brush for a polished finish.
  10. I read a book called In the Blink of an Eye not long ago where the author claimed that the development of the eye is what led to the expansion of biodiversity. I've also heard the development of hard parts, changes in environment, and genetic causes. I honestly don't have a feeling on this one. Do you?

    My Ammonite

    Hi Guys, I'm new on here and I am a 3D Artist or Artist in general from 2D Illustrations to 3D. I really enjoyed learning as a child about dinosaurs and all animals. My Dad still holds on to my old Dinosaur toys and animal cards to this day and wont give them back to have something to remember me by. I will be 3D Modeling this Ammonite and animating it. I will share my progress on here with you all. I have an image below of my fossil as well as a 3D scan of it I had done, a while back at the Siggraph animation / technology convention by 3 rivers 3D. http://www.3rivers3d.com/gallery1.html. T
  14. First off, great work guys! Some really impressive art in this section. Here's a piece I collaborated on with the eminent Sam Gon Ohu III. We did this over 10 years ago, but have gotten many requests to use it in a variety of media over the years, (recently in a text book) so I kind of dust it off a little each time and thought I'd post it here. Full explanation is on Sam's excellent trilobite site and can be found here: http://www.trilobites.info/triloclass.htm%C2'>
