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:

What evolutionary info can we cobble together about our favorite animals and plants? Take it away! P.s., I'll post mine later, since it's kinda dark AM right now.

HERE’S THE CHALLENGE! Please assist me by recommending the method you think is best for extricating fossils I know are present in the ocean rocks pictured below to the point of being “identifiable”. It has been tremendously frustrating for me to share pictures of rocks I know contain fossils, and even more so to be unable to photograph them or “clean them up” to the point where they are CLEAR. The only method of removing rock I have tried so far has been vinegar. I now have muriatic acid AND a Dremel. I have never used either before, but I have researched their usage AND “my youngest”, who is a chemistry wiz, will be home, and he has used both, (but neither on specimens that are this tiny. For example, #1 is about 1.75” x 1” OR 4.4 cm x 2.5 cm ) For rocks #1 through #8, tell me, based on the rocks, what method you think I should start with/which should be primary, for 1 or ideally for all 8. (And what kind of rock/mineral you believe it is.) Thank you! Karen

The year was 1993, the film Jurassic Park was about to be released ... The film sought to be as paleontological as possible (except for velociraptor size and Tyrannosaurus rex vision based on movement)... Very different from the current franchise that mixes the watermelon with the banana in the genetic blender forming the watermelonbananasaurus, which did not please me, and from this franchise, I never want to watch anything else! But of course, every person has a way of seeing things, and I respect it. If you like watermelonbananasaurus, what can I do? I was visiting the house of a great collector in Brazil ... Yes! The boy of the photo in 1993 is me! Just based on this photo, please, I have 2 questions and I thank all those who can help me with this great trilobita that I circled pink in the photo. 01. Does she seem to be real? 02 - At that time the fossils of Morocco were not as popular as they are today, so I do not think it is a Moroccan trilobite ... Can anyone overcome the challenge by trying to guess what specie it is? But I'm already saying that this is not a test, because I do not know either! But it's a wonderful trilobite!
