Recent molecular analyses suggest that the evolutionary history of Cingulata (Xenarthra) could be more complex than believed previously. An ancient divergence was proposed for armadillos, recognizing
Molecular divergence dating has the potential to overcome the incompleteness of the fossil record in inferring when cladogenetic events (splits, divergences) happened, but needs to be calibrated by th
A number of same species of Cerithiidae are morphologically unlike, whereas most of species in the same genus are morphologically similar and just exhibit subtle differences. It is difficult to identi
