Here goes the first paper… Feel free to ask me questions. 🙂
Bajdek, P., Szczygielski, T., Kapuścińska, A., and Sulej, T. in press. Bromalites from a turtle-dominated fossil assemblage from the Triassic of Poland. Palaeogeography, Palaeoclimatology, Palaeoecology. https://doi.org/10.1016/j.palaeo.2019.02.002
Highlights• Studied coprolites provide information on a turtle-dominated Late Triassic ecosystem.
• Coprolites were produced by sharks, turtles, theropods, and a sizable herbivore.
• Carnivores fed predominantly on fish in this fluvial environment.
• The turtle Proterochersis porebensis was likely omnivorous and semiaquatic.
• Life habits of early turtles were similar to those typical of extant taxa.February 12, 2019 at 7:49 pm #46377
Thanks for the info! Sure, I will contact you by e-mail.February 5, 2019 at 7:19 pm #46059
Very interesting, thanks for sharing, @giovanni-rios! Some time ago, I read a brief paper on dinosaur footprints from Bolivia but I can’t find it on my disk now. However, the new paper you shared mentions more than just footprints, as the Molino Formation has yielded vertebrate coprolites and teeth. The co-occurrence of dinosaur footprints and coprolites is particularly interesting to me personally, but the coprolites from the picture might have been produced by crocodiles, turtles, or even fish.February 5, 2019 at 3:09 pm #46022
You’re welcome! When I first found these fossils as a kid, I thought these were fish vertebrae!
Just search for crinoid stem fossils in Google Images. For example, this specimen looks just identical to your second picture: https://ukfossils.co.uk/2007/11/15/west-angle-bay/crinoid-stem-impression/February 5, 2019 at 2:44 pm #46020February 5, 2019 at 12:38 pm #46012
Nice list and useful. I would be happy to help with identification of possible coprolites (Trace Fossils).February 5, 2019 at 12:23 pm #46010
