Erika Posmosanu & Elizabeth Cook, Vertebrate taphonomy and dinosaur palaeopathology from a Lower Cretaceous bauxite lens, North West Romania. Oryctos 3, 39-51.
The Lower Cretaceous bauxite lens at Cornet, North West Romania, was deposited in a karstic environment as part of a system of sink holes, probably on an island in the Tethys Ocean. This bauxite lens has yielded thousands of bones and bone fragments since the initial excavations in 1978. The fauna is of restricted taxonomic diversity, and consists predominantly of ornithopod dinosaurs and rare pterosaurs. The bones have a limited size range, show a wide range of abrasion characteristics, are frequently broken and show little or no evidence of in situ weathering damage. Sorting of the skeletal elements is apparent: vertebral centra are over-represented in the collection. Of particular note are a few bones with evidence for predation or scavenging, in the form of circular punctures and elongate grooves, and pathological damage, including abnormal bone growth.
