Coprolites are the least studied and most under-sampled vertebrate trace fossils. They are very common in some Triassic localities. We recognize six new coprolite ichnotaxa: Alococopros triassicus, A. indicus, Saurocopros bucklandi, Liassococopros hawkinsi, Malericopros matleyi and Falcatocopros oxfordensis. The distribution of coprolite ichnotaxa is: Permian Hyronocopros amphipolar and Heterop...

We thank the comments of Dr Calzada. think that this kind discussions is very healthy to Paleontology and it would be necessary do more frequently, so thanks again for your example. It true some descriptions ichnofossils in our work need further discussion comments, but when we analysed several poorly-preserved specimens (such as so-called Spongeliomorpha isp.) preferred make a quick introducti...

The study of trace fossils, the fossilized remains of animal behavior, reveals interesting parallels with recent research in behavior-based robotics. This article reports robot simulations of the meandering foraging trails left by early invertebrates that demonstrate that such trails can be generated by mechanisms similar to those used for robot wall-following. We conclude with the suggestion t...
