An adult osseous head in the hippopotamus: seriated, frontal CT‐scan and reconstructions (LB5)

Abstract

The cranium and the mandible of an hippopotamus were separately CT‐scanned every 1 mm in the frontal plane. The CT‐scan was a Siemens Somatom definition AS one with 64 bars. The acquisition was performed by an helicoidal mode. 628 cross‐sections were obtained for the cranium and 669 for the mandible. About 20 reconstructions were realized. They brougth several external views under numerous incidences some of which would had been difficult to get from the dry bones as they were very large and heavy. The morphological data were very numerous especially for the study of the dental apparatus and of the intra‐cranial cavity. We acknowledge Mr Alain Piffault and Mrs Domenica Scalisi.
