During recent years, knowledge about crocodyliform diversity of the
uppermost Cretaceous from Europe has been substantially improved.
Palaeontological efforts have also been focused on microvertebrate
diversity and its palaeoecological implications. Isolated crocodylomorph
teeth are, by far, one of the most frequently recovered elements in
microvertebrate samples. In the present paper, morphological features of
crocodylomorph teeth collected throughout the complete Maastrichtian series
of the southern Pyrenean basin (north-eastern Spain), together with several
mandibular remains, are described and analysed. Teeth were grouped in
morphotypes and their taxonomic significance is discussed. The results
highlight a diverse crocodylomorph assemblage in this area throughout the
Maastrichtian. In addition, feeding habits and environmental preferences
are inferred for the identified taxa according to dental features,
occurrences and taphonomy.
