Abstract A large collection of vertebrate coprolites from black lacustrine shales in the Late Triassic (Rhaetian–Sinemurian) Kap Stewart Formation, East Greenland is examined with regard to internal and external morphology, prey inclusions, and possible relationships to the contemporary vertebrate fauna. A number of the coprolites were mineralogically examined by X-ray diffraction (XRD), showing the primary mineral composition to be apatite, clay minerals, carbonates and, occasionally, quartz… 
Fish and crab coprolites from the latest Triassic of the UK: From Buckland to the Mesozoic Marine Revolution
TLDR
The faunas and trophic relations revealed by the coprolites show that this was a modern-style marine ecosystem, with abundant crustaceans and several species of durophagous fishes, evidence for an early stage in the Mesozoic Marine Revolution.
Exceptional coprolite association from the Early Cretaceous continental Lagerstätte of Las Hoyas, Cuenca, Spain
TLDR
The sizes, inclusions, and EDX analyses indicate that the Las Hoyas coprolites correspond mostly to carnivorous producers with ichthyophagous diets, as crocodiles, urodelans and different kind of fishes.
Residues from the Upper Permian carnivore coprolites from Vyazniki in Russia - key questions in reconstruction of feeding habits
TLDR
The phosphatic composition, general shape and size, and bone inclusions of these specimens indicate that medium to large-sized carnivores, such as therocephalian therapsids or early archosauriforms, were the most likely coprolite producers.
Deep-sea ecosystem revealed by teleost fish coprolites from the Oligocene of Poland
Abstract Non-spiral coprolites likely produced by teleost fish were studied from deep-sea sediments of the Oligocene (Rupelian) of Poland. The materials were collected at the Futoma and Wola Czudecka
Bromalites from a turtle-dominated fossil assemblage from the Triassic of Poland
Abstract 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
Bromalites from the Upper Triassic Polzberg section (Austria); insights into trophic interactions and food chains of the Polzberg palaeobiota
TLDR
A rich assemblage of various types of bromalites from the lower Carnian “Konservat-Lagerstätte” from the Reingraben Shales in Polzberg is described for the first time in detail, consistent with other lines of evidence suggesting that durophagous predation has been intense during the Triassic and that the so-called Mesozoic marine revolution has already started in the early Mesozoics.
Vertebrate coprolites (fossil faeces) : An underexplored Konservat-Lagerstatte
TLDR
It is concluded that soft-tissue inclusions in coprolite are sources of two important lines of information: the fossils can be put in a direct palaeoecological context, and characters of extinct taxa are more likely preserved in the phosphate-rich taphonomic microenvironment of coprolites than elsewhere.
A new vertebrate fossil‐bearing layer in the Rhætelv Formation (Kap Stewart Group) of central East Greenland: evidence of a Hettangian marine incursion into the continental Jameson Land Basin
The Kap Stewart Group (Rhaetian‐Sinemurian, Triassic–Early Jurassic) of the Jameson Land Basin in central East Greenland has traditionally been regarded as a strictly continental unit with delta and

A coprolite association from the Barremian (Early Cretaceous) fossil site of Las Hoyas in Cuenca, central Spain, is based on 12 different morphotypes (Barrios-de Pedro et al., 2018). Most of them

ABSTRACT Cyclotosaurus naraserluki, sp. nov., is a new Late Triassic capitosaurid amphibian from lacustrine deposits in the Fleming Fjord Formation of the Jameson Land Basin in Greenland. It is
