The taxonomy and paleobiology of the Late Triassic (Carnian-Norian:
Adamanian-Apachean) drepanosaurs (Diapsida: Archosauromorpha:
Drepanosauromorpha)
By Silvio Renesto, Justin A. Spielmann,
Spencer G. Lucas and Giorgio Tarditi Spagnoli
This 81-page monograph by Renesto et al. summarizes the history
of study of drepanosaurs, photographically illustrates and describes
all
significant specimens, provides a new taxonomy and discusses the
paleobiology of the group. Two new species, Megalancosaurus endennae
and
Vallesaurus zorzinensis, are described and named. In addition, three
new
clade names are defined and established: Drepanosauromorpha =
Hypuronector + Elyurosauria; Elyurosauria = Vallesaurus +
Drepanosauridae; Megalancosaurinae = Drepanosaurus + Megalancosaurus.
This monograph provides the most comprehensive coverage of this
enigmatic group and serves as a compendium of the past two decades of
drepanosaur research.
