Lipid analysis of vertebrate coprolites [PDF]
, 2012 Lipid analysis is a relatively new approach to obtaining paleobiological and paleoecological information from coprolites. Lipids in feces are derived from multiple sources, including diet, digestive processes and digestive tract micro-organisms. Feces from herbivorous animals contain a much wider range of lipids than those from carnivores due to the ...

A king-sized theropod coprolite [PDF]
Nature, 1998 Fossil faeces (coprolites) provide unique trophic perspectives on ancient ecosystems. Yet, although thousands of coprolites have been discovered, specimens that can be unequivocally attributed to carnivorous dinosaurs are almost unknown. A few fossil faeces have been ascribed to herbivorous dinosaurs1,2,3, but it is more difficult to identify ...

The Anatomical Record, EarlyView.Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Application of Autofluorescence for Confocal Microscopy to Aid in Archaeoparasitological Analyses [PDF]
, 2019 Confocal laser scanning microscopy (CLSM) was used to examine archaeoparasitological specimens from coprolites associated with La Cueva de los Muertos Chiquitos (CMC) located near present-day Durango, Mexico.

Flying ticks: anciently evolved associations that constitute a risk of infectious disease spread [PDF]
, 2015 Ticks are important vectors of emerging zoonotic diseases affecting human and animal health worldwide. Ticks are often found on wild birds, which have been long recognized as a potential risk factor for dissemination of ticks and tick-borne pathogens ...

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
Biological Reviews, EarlyView.ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...
