Good evening to all my paleo peers! Tonight I’d like to share with you a selection of some of my favorite fossils found this year. I was lucky enough to spend three weeks in Montana over the summer, along with a few other fossil hunting opportunities here and there. As we hop into the New Year I'll kick things off aptly... Frog Radioulna-Judith River formation, Montana One of my all time best single fossil hunting days was spent in late June on a microsite in the Judith River badlands of northern Montana. Among the teeth of crocs, hadrosaurs and dromaeosaurs was this absolutely tiny limb bone. When reviewing my finds from this week I gathered up several of these micro bones and put them in a gem jar. I brought this minute group along with a small portion of my collection on my recent visit to the Carnegie Museum of Natural History. While exploring their collections I met amphibian expert Amy Henrici, who recognized it as the distinctive fused lower arm bone from a frog, also known as a radioulna. Yesterday I was able to take clear, close up pictures of this tiny limb on my digital microscope and subsequently posted it as my fossil friday on instagram (same username). I was excited to learn about its identity as it’s the first example of a frog fossil in my collection that I’m aware of! This little guy would have likely been on the menu for a whole host of predators, including Dromaeosaurs and Troodontids. The recent discovery of Daurlong provides evidence of a predator prey relationship between these two groups.
