Several occurrences of osteomyelitis in dinosaurs from a site in the Bauru Group, Cretaceous of Southeast Brazil. [PDF]
Anat Rec (Hoboken)Abstract This study investigates the occurrence of osteomyelitis in non‐avian dinosaurs, focusing on the Ibirá locality, a site with a high incidence of this pathological condition. We analyzed six new osteopathic sauropod specimens from the Upper Cretaceous of Brazil.

The origin and evolution of air sacs in pterosaurs and their forerunners. [PDF]
J AnatPneumatized pterosauromorph vertebrae and their phylogenetic context. Abstract Although the existence of postcranial pneumaticity and the inferred presence of air sacs connected to the lungs are well established in Pterosauria, the origin of this system in pterosaurs remains unclear. We investigated skeletal pneumaticity in the Triassic pterosauromorph

Trace fossils associated with Burgess Shale non-biomineralized carapaces: bringing taphonomic and ecological controls into focus [PDF]
Royal Society Open Science, 2019 The association of trace fossils and non-biomineralized carapaces has been reported from Cambrian Lagerstätten worldwide, but the abundance, ichnodiversity, taphonomy and ecological significance of such associations have yet to be fully investigated. Two

Gyrochorte “highways” and their environmental significance in shallow-marine sediments [PDF]
Acta Palaeontologica Polonica, 2020 The reworking of a trace by a subsequently following organism represents a so-called sequorichnial behavior and leads to formation of a “burrowing highway”. Burrowing highways occur more frequently than assumed in the fossil record.

Deep Learning Applications in Geosciences: Insights into Ichnological Analysis
Applied Sciences, 2021 Ichnological analysis, particularly assessing bioturbation index, provides critical parameters for characterizing many oil and gas reservoirs. It provides information on reservoir quality, paleodepositional conditions, redox conditions, and more. However,
