Aerson posted a topic in Fossil IDHello everyone. I'm a geologist/stratigraphist and I've been studying Missão Velha Formation (Araripe Basin, Brazil Jurassic-Cretaceous) for a couple of years. We found some structures that seem to be trace fossils, but as geologists, we assume ourselves to be slightly ignorant in ecologic behavior of species. The MV Formation are corsed sandstones, well stratified, with few purple siltic-sandstone levels with ped structures. These trace fossils I'll be presenting next resemble the top of one of these siltic-sandstone levels. They are tridimensional and cilindric, with an spheric edge on the bottom and the top is not well seen. It have sort of a stratification, like it was many piled up rings.
