Abstract Studies investigating paleopathologies in sauropods remain scarce despite their relative abundance in the fossil record. In this study we report new occurrence of paleopathological features, corresponding to a neoplasm found in a middle caudal vertebra (MCT.R.2120) of an advanced titanosaur from the Presidente Prudente Formation (Bauru Basin ...

Diatom fossils in mires: a protocol for extraction, preparation and analysis in palaeoenvironmental studies [PDF]
When fossil diatoms are preserved in mires, they can be excellent indicators of ecological conditions and very useful in palaeoenviromental reconstruction, both alone and in combination with other siliceous fossils.
