DeepTimeIsotopes Posted November 11, 2018 Share Posted November 11, 2018 The Confusion Range and the House Range sit in Western Utah. The House Range is farther east closer to Delta, Utah than the Confusion Range. Parts of the Confusion Range are basically on the Utah-Nevada border. Both mountain ranges though have spectacular fossils. The House Range is basically all unfaulted Cambrian age layers and fossils pop up in several of the rock layers there. The Confusion Range, though, is broken up by many faults and everything from the Cambrian to the Triassic is present. Here's a short stratigraphy section marked with the layers we visited. We went to three different sites. A Cambrian site next to U-Dig fossils to sample the Cambrian explosion, and Ordivician site at Fossil Mountain (what better place to find fossils then a mountain named "fossil" mountain) to sample the Great Ordivician Biodiversification Event, and finally a time where 90% of all marine was wiped out, the Permian Period and the Gerster Limestone. 11 Each dot is 50,000,000 years: Hadean............Archean..............................Proterozoic.......................................Phanerozoic...........

DeepTimeIsotopes Posted November 11, 2018 Author Share Posted November 11, 2018 Stop 1: the Cambrian Some highlights: Most of had previously collected here so we did not spend a lot of time here. The smaller dots to the left are not Bivalve shells as one would expect but rather are inarticulate Brachiopods, Acrothele subsidua. This one is nice because both halves are there. The trilobite is the Utah State invertebrate fossil: Elrathia kingii 6 Each dot is 50,000,000 years: Hadean............Archean..............................Proterozoic.......................................Phanerozoic...........

DeepTimeIsotopes Posted November 11, 2018 Author Share Posted November 11, 2018 (edited) Stop 2: the Ordivician Fossil Mountain is aptly named. There are tons of fossils to be found. Tons of trilobites, brachipods, bryozoans: the classic Paleozoic fossils. In the sandstones, were near shore trace fossils in this case: Skolithos The limestones though were where the body fossils were at. Right of the chisel edge of my hammer is a trilobite pygidium. In this case it is from Jenkinsonia varga. Edit: the trilobite pygidium is more likely Kanoshia kanoshensis rather than Jenkinsonia varga as @piranha has pointed out.

DeepTimeIsotopes Posted November 11, 2018 Author Share Posted November 11, 2018 Stop 3: the Permian By the time the Gerster Fm. was layed to rest for the next 252 million years the trilobites had gone extinct all that remains at this locality is brachipods, bryozoans, and bivalves. The trilobites had gone extinct here. Most of what we found was Timaniella pseudocamerata but there were a lot of bryozoan colonies and brachipods as well. 3 Each dot is 50,000,000 years: Hadean............Archean..............................Proterozoic.......................................Phanerozoic...........

DeepTimeIsotopes Posted November 11, 2018 Author Share Posted November 11, 2018 Stop 3: continued Absolute gorgeous area This has been a trip through the 289 million years of the Paleozoic. Starting in the cradle of the Cambrian ending in the deathbed of the Permian for many of these organisms. This has to have been one of my favorite trips to date.
