Overview of computational methods in taphonomy based on the combination of bibliometric analysis and natural language.

Artificial intelligence tools are new in taphonomy and are growing fast. They are being used mainly to investigate bone surface marks. In order to investigate this subject, a bibliometric study was made to understand the growing rate of this intersectional field, the future, and gaps in the field until now.

Protozoan parasites of birds from the Tremembé formation (Oligocene of the Taubaté Basin), São Paulo, Brazil.

Objective: To analyze the presence of protozoan parasites in bird coprolites from the Tremembé Formation (Oligocene of the Taubaté Basin).

Materials: Twenty avian coprolites embedded in pyrobituminous shale matrices.

Methods: Samples were rehydrated and subjected to spontaneous sedimentation.

Bibliometric analysis of isotopic studies on Quaternary megafauna available in the Scopus database.

The number of isotopic studies on Quaternary megafauna has increased over the last decades, yet, there is no published data addressing the status of scientific production of this research field. The present study shows the results of a bibliometric research carried out in the Scopus database where the publishing trends within this scientific field was analyzed using the open source software tool SciMAT. We retrieved 278 papers published from 1980 to 2019 and observed that a significant increase in publishing has mainly occurred in the last decade analyzed here.

Neck osteoarthritis in Eremotherium laurillardi (Lund, 1842; Mammalia, Xenarthra) from the Late Pleistocene of Brazil.

Paleopathological analyses of Brazilian Quaternary mammals remain scarce. However, this type of study can shed light on several paleoecological issues in vertebrate paleobiology and taphonomy. Here, we describe and diagnose a pathology on an axis of a ground sloth Eremotherium laurillardi (Lund, 1842) from Pernambuco State, Brazil.
