    Hi Guys,

    Need help IDing this micro bones. They are part of more than 20 microbones including femurs less than .5” long. Amphibians?

    These to me look more fish-like (either ribs or spikes). If ribs, they curve downwards which would mean this fish is taller than wide and was probably not a bottom feeder or dweller. Maybe @vperez or @jeanette-pirlo might know.

    Hello,

    I believe these are angulosplenials of Anurans. I’m not sure how to narrow down to genus level or even whether it’s from a frog or toad though.

    @rnarducci @mackenzie-smith @vperez Found the culprit! They are the lower Jawbones of Rana catesbeiana. Given the locality early Pleistocene. See ilustration below.

    Hi @alex-rosas

    I agree that they are frog bones, but I’m not certain they are diagnostic to the species level. The associated bones found in the same 1ft square might be from the maxilla or premaxilla. I’ll see if someone over in herpetology can tell us more.

    Best,

    Victor
