Reproductive Traits of Non-avian Theropods

  title={Reproductive Traits of Non-avian Theropods},
  author={Darla K. Zelenitsky},
The reproductive biology of non-avian theropods, primarily maniraptorans, is revisited using recent fossil discoveries in the framework of the extant phylogenetic bracket. It is apparent that non-avian theropods shared some reproductive characters with crocodilians, some with birds, but also possessed their own unique features. Whereas the non-avian theropod reproductive system retained primitive archosaurian traits (two functional oviducts, hyper-ellipsoidal eggs), it also possessed derived… CONTINUE READING
