Presentation

My work aims at improving our understanding of the patterns of morphological evolution in deep time, using mostly the diversification of extinct and extant South American placentals as a model. My studies on these aspects follow three main objectives:

  • describing and analyzing the patterning of unusual morphological variations, at different hierarchical levels (eg, ontogenetical, interspecfic, inter-individual)
  • studying potential links between these patterns of morphological variation and functional characteristics
  • searching for a phylogenetic signal in morphological data and improving our use of this kind of data for phylogenetic reconstructions and placement of fossil taxa
