I love your informative videos. You prove excellent information. I live in Utah and would like to perhaps visit some of the rocks you discuss in your videos. I don't have formal training in geology or paleontology, but am fascinated with the diverse rock formations and fossils that can be found here in Utah.
Great use of the drone footage at 8:10 showing the bedding from above. This retired Midwest geologist planning a trip loved the review. Looking forward to a summer motorcycle trip through Utah/Montana this summer... hope to be swinging the Ol' Estwing a time or two.
Not that I'm aware of, the Mowry Shale is wedged between the "Dakota or Muddy" and "Ferron and or Frontier" Sandstones, and represents the Max. Flooding Surface, with the finest grains in the sequence. Fairly deep waters with this first major transgression cycle to produce black shales. The ocean basin was likely shallow, with out much canalization, although when you get higher in section with the Mancos Shale, I've seen some good turbidites and canalization, with evidence of a steeper slope.
a pleasure to listen to someone who is so knowledgeable and who can convey that knowledge with such precision and passion. i just wish you were talking about the fossils of the British isles .
Great information and presentation. As I and I am sure others are not familiar with these great historical epochs of times it would help if you told us the time elements in the description (attention grabber}. I would look like to go though these events is sequence. Thank you for sharing.
knowledge just for the beauty of knowledge. Good stuff. Took me back to my graduate thesis days in examining the brachiopod Conchidium Laqueatum (Middle Silurian; Niagaran)
Benjamin, I am looking to see if you might help me. I grew up in Up state New York where they have shale formations in many of the creeks. I was wondering if you might be able to help find some approximate dates on when that might have formed. thank you
Dr. Burger, (it's clear you have earned a PhD as you were gaining this wealth of knowledge) this is a wonderful explanation of how iron sulfide formed on these shells! My avocation is chemistry and I enjoy hearing this type of mix of the disciplines. Thanks for that discussion because it relates to so many other areas where iron sulfide can be found. As you were discussing this I felt a little sadness that the quality of these beautiful specimens is probably in the process of degrading or oxidizing, now that they are exposed to atmospheric oxygen. Thanks for sharing.
Western TN was above sea level at the time so it was eroding, thus no record of marine fossils or evidence of Cretaceous fossil, the theme of this vid.

Have you ever found evidence of canalization within the HST shales? maybe filled with silt or fine sand? Thanks.

The flaky crinkling sounds of shale is music to my ears.
unibrowsheepZ I know right?

One question.. What lived in Tennesee, particularly, west TN at the time the Mowry shale was being laid down?
Western TN was above sea level at the time so it was eroding, thus no record of marine fossils or evidence of Cretaceous fossil, the theme of this vid.
12:31 Couldn't have said that better myself.
Wes Turner ahahah, true
Omg, you took your hat off!!! xD
Great video, as always!!!
I almost jumped ahead just to see. Ahhh, I'll wait :)
