Excellent response. There are non-marine layers that bear Permian vertebrate tracks in the Grand Canyon.

@@bjnslc Yes, I was actually going to address that in my 2nd video. You have the Coconino Sandstone which is an Aeolian deposit.

42:40 The fossil mammal shown is an Apatemyid and not a primate. Apatemyids don’t have any close living relatives as far as mammals go and it is not surprising that many groups of plants and animals don’t exist today if deep time is correct.

16:40 This is incorrect actually. I agree that there are varves in the Green River Formation but these fossil dense sections that are quarried commercially are laminated sediments that were deposited by storms along the shoreline of the Fossil Lake, which lacks varves. Actual varves have been described from the Tipton, Laney, and Wilkins Peak members that formed in Lake Uinta and Gosiute. Fossils in these truly varved sequences are nearly absent and always poorly preserved because such carcasses would require at least somewhat rapid burial to be preserved as creationists suggest , though it was probably much slower than what they are arguing in most cases (at most, weeks to months rather than instantaneous. I would suggest you read some articles about creationist claims on the Green River formation by Mountain Railroad and Kevin Henke (I can’t link them here because my comment would get flagged as spam) , as they go into great detail refuting a lot of the misinformation that has been spread online about these deposits.

I really appreciate you pointing this out to me. I was under the impression that all of the Green River Formation has varve sequences. I didn't know was only limited to certain sections within the formation.
