Adelolophus, Gongpoquansaurus, Plesiohadros abstracts (old)

I've had problems sending posts to the DML this morning, so I'll see
if this one gets through. These abstracts were included in a bigger
post with older refs, but it has been repeatedly blocked so I'm
dividing it up to see what happens.

These refs were posted in 2014 without abstracts. Here are the abstracts:

Plesiohadros

K. Tsogtbaatar, D. B. Weishampel, D. C. Evans and M. Watabe (2014)
A new hadrosaurid (Plesiohadros djadokhtaensis) from the Late
Cretaceous Djadokhtan Fauna of southern Mongolia.
Hadrosaurs: 108-135

The Djadokhta Formation (Campanian) has been intensely surveyed and
sampled for its fossil vertebrate fauna for almost a century. Its
dinosaur fauna is historically defined as being dominated by the
ornithischians Protoceratops and Pinacosaurus, as well as oviraptorid
theropods, but recent collecting efforts continue to yield new taxa.
Here we describe and name the first ornithopod from this unit. The
material consists of an almost complete skull and associated limb
material collected from the Alag Teeg locality. Plesiohadros
djadokhtaensis nov. gen. et nov. sp. is characterized by a unique
combination of plesiomorphic and derived characters within
Hadrosauroidea, and an autapomorphically rugose, raised rim around the
rostrodoral margin of the orbit. In order to place P. djadokhtaensis
into its paleoecological and stratigraphic context within these Upper
Cretaceous rocks of Mongolia, we also provide a review of the
geological setting of the Djadokhta Formation in the Gobi Desert.
Plesiohadros is the largest member of the Djadokhta fauna, and the
only known hadrosauroid from the Campanian of Mongolia. An updated
phylogenetic analysis indicates that P. djadokhtaensis is a derived
hadrosauroid proximate to Hadrosauridae (sensu Sereno). Plesiohadros
is posited as the sister taxon to a clade that includes Lophorhothon
and Hadrosauridae, and is more closely related to Hadrosauridae than
to Bactrosaurus, Telmatosaurus, or Tethyhadros. The complete
replacement of non-hadrosaurid hadrosauroids with true hadrosaurids in
the Maastrichtian of Mongolia highlights the complex pattern of faunal
interchange between Asian and North America in the latest Cretaceous.

Gongpoquansaurus

H.-l. You, D.-Q. Li, and P. Dodson (2014)
Gongpoquansaurus mazongshanensis (Lü, 1997) comb. nov. (Ornithischia:
Hadrosauroidea) from the Early Cretaceous of Gansu Province,
northwestern China.
Hadrosaurs :73-76

This chapter proposes a new generic name “Gongpoquansaurus” for
“Probactrosaurus” mazongshanensis Lü, 1997. Gongpoquansaurus
mazongshanensis comb. nov. is a basal hadrosauroid distinguishable
from other taxa by the unique combination of these cranial features:
transversely elongated supratemporal fenestra, broad and flat dorsal
surface of the parietals with a deep median groove, and large and
straight nuchal crest. Recognizing its own generic status, rather than
as a species of Probactrosaurus, increases basal hadrosauroids to four
genera in the Early Cretaceous Mazongshan area of northwestern Gansu
Province, China.

Adelolophus

T. A. Gates, Z. Jinnah, C. Levitt and M. A. Getty (2014)
New hadrosaurid (Dinosauria, Ornithopoda) specimens from the
lower-middle Campanian Wahweap Formation of southern Utah.
Hadrosaurs: 156-173

Hadrosaurid ornithopods from the early to middle Campanian are rare in
North America, but the Wahweap Formation of southern Utah yields
specimens that are increasing the known diversity of hadrosaurids from
this poorly understood time period. A new genus and species of
lambeosaurine hadrosaurid, Adelolophus hutchisoni, is described on the
basis of an isolated maxilla. This single element is distinct from all
other known lambeosaurine hadrosaurid maxillae in the large medial
wall, raised palatine process, and other features associated with the
raised medial wall. Another locality in the middle of the Wahweap
Formation yielded two individuals of presumably the same species, an
adult and a juvenile. The specimens show autapomorphic morphology of
the caudal vertebrae neural spines and centra, along with a unique
suite of iguanodontian characters. Given that the only diagnostic
skull elements belong to the juvenile individual, the phylogenetic
position of this species is unclear, although the postcranial skeleton
possesses a mix of primitive and derived traits. The site represents a
swampy environment containing autochthonous specimens; among these,
long bones exhibit slightly preferred orientations.

These new taxa appear in the book Hadrosaurs from Indiana University
Press. The publication date is given as 11-5-2014 and material has
started to appear on the web, although the publisher's website still
says it's not yet published (likely needs to be updated). Many thanks
to people who noted that a preview of the book is up in Google
Books--I waited in case any embargoes were in force. I assume it's now
OK to mention these. May have abstracts in the near future...
