Mid-Mesozoic Field Conference, Day 4: Into the Lower Cretaceous
May 3, 2014
A short post this time, partly because it’s late, partly because the hotel internet is sucking bigtime–probably as the hotels fill up for the weekend. I simply don’t have the bandwidth to post more, and in fact I had to downsize these few photos to get them to upload in polynomial time.
Today we left Fruita, Colorado, and hit several Lower Cretaceous sites in eastern Utah on our way to Green River, Utah. Highlights were the Copper Ridge and Mill Canyon dinosaur tracksites.
Here’s a tridactyl theropod track between two sauropod pes prints at Copper Ridge.
Here’s a little theropod track at Mill Canyon…
…a big one…
…and one that I had never seen before in person: Dromaeosauripus, the two-toed ichnogenus left by dromaeosaurs. Utahraptor or a close relative is a likely culprit for the Mill Canyon Dromaeosauripus.
