Biogeographic distribution of infected plants and the continental drift theory allow a tentative time calibration of the phylogenetic tree of Pospiviroidae. Hypothetically, viroids evolved in the late Early Cretaceous shortly after the appearance of

In 2016 two coprolites were discovered behind the stronghold palisade on the north-west slope facing the lake. Layer 4, from which they were recovered, was created by the accumulation of settlement waste. In addition to analysing their microstructure

Bromalites (coprolites and possibly some cololites) from a turtle-dominated fossil assemblage from the Upper Triassic of Poland were studied. Bromalites collected at the Poreba site are grouped within four morphotypes (A, B, C, and D) attributable to

mtDNA-based phylogenetic trees of the order Primates were constructed by the minimum evolution (ME) and maximum likelihood (ML) methods. Branch lengths were compared with the mean female age at first birth in the taxa studied. Higher reproductive age

Oncoids are rare components of Keuper sediments across Europe. The exceptions are localities linked to the Upper Triassic "Wozniki Limestone" (formally Limestone Member from Wozniki) in Silesia, so ...

Vertebrate trace fossils often provide a measure of cryptic biodiversity, and are especially pertinent when skeletal remnants are exceptionally rare. The Lower Triassic (lower Olenekian) Bulgo Sandstone at Long Reef in the Sydney Basin of southeaster

Coprolites (fossil faeces) provide direct evidence on the diet of its producer and unique insights on ancient food webs and ecosystems. We describe the contents of seven coprolites, collected from the Late Permian Vyazniki site of the European part o

This study investigates the paleoecological significance of vertebrate coprolites collected from seven sections and three lithofacies of the uppermost Permian and lowermost Triassic succession from the Vyazniki site in the European part of Russia. Th

The oldest feathers known to date have been found in archosaurs capable to fly. However, some of them (scansoriopterygids) flied by the use of a membrane rather than feathers. We therefore propose a new mechanism for the origin of avian flight by the

It is widely accepted that birds evolved from theropod dinosaurs, and few paleontologists disagree preferring a more ancient split of the avian and dinosaur lineages. The difference in digestive physiology between members of the theropod and crocodil
