ProposalDescription: 

The aim of the project is to perform a detailed study of the teeth microstructure of burrowing mammal-like reptiles (such as Thrinaxodon) to understand their adaptations facing the dramatic climatic modifications of the Early Triasic (-252 Million years ago). As these mammal-like reptile were replacing their teeth throughout their live, the rapid mineralization of the bony part of their teeth (the dentine) was affected by environmental variation and metabolic strategies to survive critical part of the year (drought). For each different individual we have the opportunity to assess the stress from the environment at various period of their growth. It will allow us to get new information regarding their thermophysiology (if they were cold-blooded or warm-blooded animals) and if they were experiencing long torpor during periods of drought (called, aestivation, the summer counterpart of hibernation): If the animals were indeed aestivating as it is suggested by many studies, the mineralization of teeth completely stopped during these periods and it will be visible by line of arrested growth. This study will permit to clarify whether or not this animal were using this.
