Microbiota and food residues including possible evidence of pre‐mammalian hair in Upper Permian coprolites from Russia
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… Expand

Synchrotron phase-contrast microtomography of coprolites generates novel palaeobiological data
Coprolites (fossil faeces) reveal clues to ancient trophic relations, and contain inclusions representing organisms that are rarely preserved elsewhere. However, much information is lost by classical… Expand

Reduction of vertebrate coprolite diversity associated with the end-Permian extinction event in Vyazniki region, European Russia
Abstract This study investigates the paleoecological significance of vertebrate coprolites collected from seven sections and three lithofacies of the uppermost Permian and lowermost Triassic… Expand

Vertebrate coprolites (fossil faeces) : An underexplored Konservat-Lagerstatte
Abstract Fossilized soft tissues of animals (e.g. muscles, hair and feathers) are valuable sources of palaeobiological information, but a poor preservation potential makes them undesirably scarce in… Expand

The first direct evidence of a Late Devonian coelacanth fish feeding on conodont animals
We describe the first known occurrence of a Devonian coelacanth specimen from the lower Famennian of the Holy Cross Mountains, Poland, with a conodont element preserved in its digestive tract. A… Expand

Trace and rare earth element compositions of Silurian conodonts from the Vesiku Bone Bed: Histological and palaeoenvironmental implications
Abstract In-situ minor, trace and rare earth element (REE) compositions have been measured in conodonts from the lower Silurian Vesiku Bone Bed (Estonia), with the aim to visualize and to quantify… Expand

Beetle-bearing coprolites possibly reveal the diet of a Late Triassic dinosauriform
Diets of extinct animals can be difficult to analyse if no direct evidence, such as gut contents, is preserved in association with body fossils. Inclusions from coprolites (fossil faeces), however,… Expand

Tyrannosaurid-like osteophagy by a Triassic archosaur
Here we present evidence for osteophagy in the Late Triassic archosaur Smok wawelski Niedźwiedzki, Sulej and Dzik, 2012, a large theropod-like predator from Poland. Ten medium to large-sized… Expand

Non-marine palaeoenvironment associated to the earliest tetrapod tracks
Opinions differ on whether the evolution of tetrapods (limbed vertebrates) from lobe-finned fishes was directly linked to terrestrialization. The earliest known tetrapod fossils, from the Middle… Expand

A new charophyte flora from the Upper Triassic of Skane (Sweden) and implications on biostratigraphy, taphonomy and the palaeoenvironment
Abstract The record of fossil charophytes from Sweden was previously restricted to the Ladinian-earliest Carnian Falsterbo Formation. Here, we present a charophyte assemblage from the Upper Triassic… Expand
