Abstract
Armadillosuchus arrudai, an extinct crocodyliform, has a complex pattern of tooth replacement. Replacement of functional teeth followed an alternating numerical and directional wave from posterior to anterior. Notably, the presence of an initial fossa in some teeth indicated root resorption and facilitated the development of tooth replacement. These aspects suggest a coordinated tooth replacement process, enabling the animal to maintain functional dentition. This study provides insights into the unique dental dynamics of Armadillosuchus arrudai, highlighting its lifelong polyphyodonty and the meaning of alternating replacement patterns. Microtomography allowed the comprehension of these intricate tooth replacement processes.
期刊介绍：
Cretaceous Research provides a forum for the rapid publication of research on all aspects of the Cretaceous Period, including its boundaries with the Jurassic and Palaeogene. Authoritative papers reporting detailed investigations of Cretaceous stratigraphy and palaeontology, studies of regional geology, and reviews of recently published books are complemented by short communications of significant new findings.
Papers submitted to Cretaceous Research should place the research in a broad context, with emphasis placed towards our better understanding of the Cretaceous, that are therefore of interest to the diverse, international readership of the journal. Full length papers that focus solely on a local theme or area will not be accepted for publication; authors of short communications are encouraged to discuss how their findings are of relevance to the Cretaceous on a broad scale.
Research Areas include:
• Regional geology
• Stratigraphy and palaeontology
• Palaeobiology
• Palaeobiogeography
• Palaeoceanography
• Palaeoclimatology
• Evolutionary Palaeoecology
• Geochronology
• Global events.
