An Overview of Non-Avian Theropod Discoveries and Classification.
PalArch’s Journal of Vertebrate Palaeontology 12: 1 (2015): 1-73
ISSN 1567-2158


Theropods form a taxonomically and morphologically diverse group of
dinosaurs that include extant birds. Inferred relationships between
theropod clades are complex and have changed dramatically over the
past thirty years with the emergence of cladistic techniques. Here, we
present a brief historical perspective of theropod discoveries and
classification, as well as an overview on the current systematics of
non-avian theropods. The first scientifically recorded theropod
remains dating back to the 17th and 18th centuries come from the
Middle Jurassic of Oxfordshire and most likely belong to the
megalosaurid Megalosaurus. The latter was the first theropod genus to
be named in 1824, and subsequent theropod material found before 1850
can all be referred to megalosauroids. In the fifty years from 1856 to
1906, theropod remains were reported from all continents but
Antarctica. The clade Theropoda was erected by Othniel Charles Marsh
in 1881, and in its current usage corresponds to an intricate
ladder-like organization of ‘family’ to ‘superfamily’ level clades.
The earliest definitive theropods come from the Carnian of Argentina,
and coelophysoids form the first significant theropod radiation from
the Late Triassic to their extinction in the Early Jurassic. Most
subsequent theropod clades such as ceratosaurs, allosauroids,
tyrannosauroids, ornithomimosaurs, therizinosaurs, oviraptorosaurs,
dromaeosaurids, and troodontids persisted until the end of the
Cretaceous, though the megalosauroid clade did not extend into the
Maastrichtian. Current debates are focused on the monophyly of
deinonychosaurs, the position of dilophosaurids within coelophysoids,
and megaraptorans among neovenatorids. Some recent analyses have
suggested a placement of dilophosaurids outside Coelophysoidea,
Megaraptora within Tyrannosauroidea, and a paraphyletic
Deinonychosauria with troodontids placed more closely to avialans than

Subject: Blocked post for new theropod paper...

I have tried repeatedly today to send a post the DML for a new
monograph on theropod classification in the open access journal
PalArch. Every attempt has been blocked, likely by the DML spam filter
for some unexplained reason. I don't know what is causing the posts to
fail--something in the title, the url, or the abstract. Before I try
again, has anybody received my posts?

I monitored another email site and a "live" DML blog post site. My
other posts got through today but the new theropod paper item (sent
multiple times as three separate messages after all other attempts
failed, even with Forward) has not appeared..

Here's the general url.
