Abstract Rare assemblages of woody coprolites from different strata of the Two Medicine Formation provide surprising perspectives on the feeding behavior of Late Cretaceous ornithischian dinosaurs. Most of the irregularly shaped, calcareous specimens are largely composed of fragmented conifer wood (13%–85%) and can be identified as coprolites by the presence of distinctive backfilled dung beetle burrows. The large size (up to 7 L in volume), fibrous contents, and associated bones and eggshell… 

Early Jurassic coprolites: insights into palaeobotany and the feeding behaviour of dinosaurs

Analyses of coprolites provide important data on animal feeding and food quality, including information on the taxonomy of the biotope. Knowledge of the diet of extinct animals has implications for

Coprolite morphotypes from the Upper Cretaceous of Sweden: novel views on an ancient ecosystem and implications for coprolite taphonomy

TLDR
The collective data from the Asen coprolites provide new insights into a shallow-water Late Cretaceous marine ecosystem hitherto known solely from body fossils.

Consumption of crustaceans by megaherbivorous dinosaurs: dietary flexibility and dinosaur life history strategies

TLDR
F fossilized feces (coprolites) that demonstrate recurring consumption of crustaceans and rotted wood by large Late Cretaceous dinosaurs are described and reveal a degree of dietary flexibility that is consistent with that of extant herbivorous birds.

Beetle-bearing coprolites possibly reveal the diet of a Late Triassic dinosauriform

TLDR
It is hypothesized that the beak-like jaws of S. opolensis were used to efficiently peck small insects off the ground, a feeding behaviour analogous to some extant birds.

FEEDING TRACES AND PALEOBIOLOGY OF A CRETACEOUS (CENOMANIAN) CROCODYLIFORM: EXAMPLE FROM THE WOODBINE FORMATION OF TEXAS

TLDR
The morphology of the new crocodyliform taxon and the distribution of bite marks indicates it was likely a generalist: an opportunistic predator that fed on a variety of prey, including turtles and dinosaurs.

Dietary palaeoecology of an Early Cretaceous armoured dinosaur (Ornithischia; Nodosauridae) based on floral analysis of stomach contents

TLDR
Details of the dietary palaeoecology of this nodosaur are revealed, including: selective feeding on ferns to the exclusion of Osmundaceae and eusporangiate f Ferns such as Marattiaceae; and incidental consumption of cycad–cycadophyte and conifer leaves.

Bacterial Residues in Coprolite of Herbivorous Dinosaurs: Role of Bacteria in Mineralization of Feces

TLDR
Observations suggest that bacteria within the capillaries induced initial mineralization of the coprolite, and, in so doing, created barriers that protected organic residues from subsequent destruction.

Wood Decay in Silicified Gymnosperms from Antarctica

TLDR
Gymnospermous secondary xylem degraded by wood-decaying fungi was examined in silicified fossils from Antarctica, and indications of host response to fungal attack include the production of possible wall appositions.

GUT CONTENTS FROM A CRETACEOUS TYRANNOSAURID: IMPLICATIONS FOR THEROPOD DINOSAUR DIGESTIVE TRACTS

TLDR
It appears that Daspletosaurus and most theropods ingested and digested prey in a manner similar to that of extant archosaurs, employing a two-part stomach with an enzyme-producing proventriculus followed by a thick-walled muscular gizzard.

ABSTRACT The diversity of cranial and postcranial elements of dinosaur remains, early mammals and palynomorphs in the Aguja Formation (Campanian) rivals many other Upper Cretaceous localities.

Dinosaur Coprolites and the Early Evolution of Grasses and Grazers

TLDR
Phytoliths extracted from the coprolites suggest that the suspected dung producers (titanosaur sauropods) fed indiscriminately on a wide range of plants, and make plausible the hypothesis that gondwanatherian mammals with hypsodont cheek teeth were grazers.

TLDR
The presence of wood decay coupled with a septate mycelium suggests the presence of higher fungi in the Devonian and indicates a more diverse Devonian mycoflora than has previously been recognized.
