Research to answer a 'crushing' evolutionary question

(New Jersey Institute of Technology) Studying the physical features of long-extinct creatures continues to yield surprising new knowledge of how evolution fosters traits desirable for survival in diverse environments. Placodonts are a case in point -- specifically, the placodont teeth that Stephanie Crofts, an NJIT post-doctoral researcher, has written about in an article recently published in the journal Paleobiology.
