Is there any herbivorous pterosaur in the deep time?
Pterosaur is the first group of vertebrates with powered flight. It originated in the Late Triassic and became extinct with dinosaurs (excluding birds) at the end of the Cretaceous. Various diets of pterosaurs were proposed using different interpretations, such as content fossils and comparative anatomy. However, the understanding of the diets of many pterosaurs have still been on debate, which is mainly because of the rarity of stomach content found in pterosaurs. In this paper, the researchers found an elliptical content in the stomach position of a Sinopterus specimen. They extracted more than 300 phytoliths from the stomach content but none from the matrix of the same specimen. This demonstrates that these phytoliths, firstly appeared in pterosaurs, were eaten by this Sinopterus rather than any pollution after its death. Phytolith is a microstructure produced by all kinds of plants, and it varies among different plants and different positions of the same individual. Besides the phytoliths, many gastroliths (stones within the body cavity) were also discovered in the stomach content, which is the second pterosaur specimen with gastroliths. The combination of phytoliths and gastroliths, without any bones, scales or exoskeletons, strongly suggest that Sinopterus is herbivorous.

I always feel impressed when I see him, he is huge, not always in his brightest colors, but always impressive.

#FossilLeaves reveal drivers of herbivore functional diversity during the #Cenozoic https://www.pnas.org/doi/10.1073/pnas.2300514120
"the diversity of #herbivorous #insects evolved over the last 60 million years primarily through the shared use of food #plants. The results are based on the analysis of feeding traces left by #arthropods on more than 45,000 fossil leaves."
Feeding traces on fossil leaves help researchers identify factors leading to enormous herbivore diversity
Researchers from the Hessian State Museum Darmstadt and the Senckenberg Biodiversity and Climate Research Center Frankfurt have uncovered the factors that determine the enormous diversity of herbivorous insects.

#Diplodocids were large #herbivorous #dinosaurs with long necks and long tails. In a previous study, it was believed that a hypothetical structure at the end of a diplodocid's tail, similar to the end of a whip, could move faster than the speed of sound (340 meters per second) and produce a #supersonic bang.

It's always heartwarming to see does with the young ones. Unlike stags, a doe shows a way more affection towards the fawns, especially to other young does which they may form a herd with.
