    I’d agree with what Andy said, it’s certainly the femoral head of a mammal. Due to its fragmentary nature and lack of scale or geologic context, I can’t go further than that.

    Yep! It’s a lower horse tooth. It’s a little trickier to tell the age of it, but Miocene or Pliocene seems likely.

    I think Evan is right on. Certainly looks like White River preservation to me. To narrow it down, it is the lower right jaw with the first and second molars of an oreodont, not Mesohippus. Without knowing where in the White River stratigraphy it came from and with no premolars present it’s hard to say which oreodont species it is, but like Evan said it could be Merycoidodon sp. or possibly Miniochoerus sp.

    Well, it’s certainly the distal half of a right humerus (the part of the bone that articulates with the radius and ulna). Based on size, and not having any idea how old it might be, I’d have to go with something like a deer, but distal humeri in some animals can be pretty difficult to tell apart so that’s by no means definitive.

    Yeah, I think it’s most likely a bison right upper third premolar…that’s my best guess.

    Hi all!

    Sorry I’m a little late to the party. Now that I’ve been called out I guess I can’t hide anymore.

    I’m going to go a little off script from @jeanette-pirlo‘s original questions, but here it goes:

    I grew up in the south Jersey suburbs of Philadelphia (E-A-G-L-E-S EAGLES!!!…sorry I’m a Philly fan, these opportunities don’t come around very often) and fell in love with fossils and paleontology in middle school. Early in high school I began volunteering at our local natural history museum in Philly and was lucky enough to start traveling to Montana to dig up dinosaurs a couple summers later. I graduated with a B.S. in geology for the College of William and Mary in 2011 and did research on the formation of 120 and 66 million year old fossil sites with high concentrations of vertebrate fossils called microsites.

    From 2011-2014 I worked on my masters in geology with Bruce looking at the diet and paleoclimate of 18 million horses using the chemical composition of their tooth enamel. I was a little confused about what I wanted to do upon finishing my masters before a couple opportunities to work with high school teachers in Ohio and California popped up through Bruce’s connections. So from 2014-2016 I visited many classrooms of all grade levels, worked on developing curricula, and dabbled in education research. After that two year hiatus I began working on my PhD in Zoology (and a likely minor in science ed!) at UF and am just starting to nail down what my research will be.

    I’m really interested in a period of time ~34 million years ago known as the Eocene-Oligocene Transition, or the EOT. One of the many things that is really fascinating about the EOT is that it’s largest mass extinction since the extinction of the dinosaurs, although the terrestrial animals living in North America don’t seem to be as affected as marine animals or land animals in other parts of the globe. We’re pretty sure this devastation was caused by a sudden drop in global temperatures, as evidenced by the formation of ice caps in Antarctica at that time, but we’re not really sure what caused the plummet in temperature. My PhD research will look at fossils from Nebraska to try to identify some of the changes that occurred in the mammals during that time and take a closer look at how much of the temperature shift was actually felt by the animals on land.

    It’s really fun, interesting stuff and I’m planning to spend over a month after our New Mexico adventure digging up fossils in Nebraska! I can’t wait for July!

    In terms of the GABI…it has to go down as one of the most interesting evolutionary experiments to ever occur in the history of our planet. And, unlike some other similar hypothesized events, we actually have the mountains of fossils and data needed to tell the story with some amount of accuracy, but it’s far from complete! It would be amazing if we could add our little piece to the story with the field work we’ll be doing over the next 6 months.

    • Hello everyone,

      Its a pleasure to part of this group and I am honored.
      1. I was born in Mexico City and I found my first fossil in Veracruz. It was a beautiful spiral shell.
      2. I teach in Santa Cruz at Gault Elementary. I have taught third grade for 4 years.
      3. I find the idea of people studying the history of the genetic pool of past Earths fascinating and I really look forward to learning from all of the group and with the experience in the field.
      4. I think I would like hear ideas from expert on how to create a lesson that includes an engineering standard and bring that into the classroom.
      5. I would like to also learn how to find a place with the probability of fossils. What do scientist look for in the sediment. Where do you get records of the the sediment.

      • Thanks for joining us Isai! Engineering standards can be difficult at first, but I believe that this experience will help you figure out how to incorporate them. Understanding the stratigraphy of a site is also important. My lab mate, @smoran can do a better job at explaining how to find fossils, based on the visible sediment.

    Sorry @muhammad-usman not sure I’m going to be of much help here either. I’m pretty confident saying it’s a fragment of a mammal lower jaw bone with two roots still in the mandible. Unfortunately, without the crown of the teeth preserved I’m not familiar enough with fossils from the Siwaliks to go much further than that.
