Abstract

Two fragmentary coprolites from the Lower Cretaceous Jydegaard Formation of Bornholm, Denmark, represent the first record of coprolites from continental Mesozoic deposits in Denmark. Both specimens contain fish scale bone fragments of unknown affinity. Based on morphology, inclusions and the potential producers found in the Jydegaard Formation, we suggest they were made by either a turtle or a theropod with a piscivorous diet.
One specimen shows pits and grooves in the surface, as well as two deep cylindrical burrows, made by coprophagous organisms.
