Beetle elytra and other arthropod remains have been found in coprolites  which have been recovered in the vicinity of Silesaurus fossil occurrences.
The size and shape of the coprolites combined with the peculiar beaked architecture of Silesaurus's skull may suggest that this animal produced the coprolites and that it could have been wholly or partially insectivorous.
It might have fed on insects and other small arthropods by pecking, using the beak-like tip of the snout to accurately target prey in a way similar to modern birds.
If so, this would represent the earliest known occurrence of this highly derived mode of feeding and have implications for the understanding of  the evolutionary adaptations that would eventually lead up to the origin of dinosaurs.
