A new dromaeosaurid (Dinosauria: Theropoda) from the Upper Cretaceous
Wulansuhai Formation of Inner Mongolia, China.
Zootaxa 2403: 1–9 (19 Mar. 2010).
We describe a new dromaeosaurid theropod from the Upper Cretaceous
Wulansuhai Formation of Bayan Mandahu, Inner
Mongolia. The new taxon, Linheraptor exquisitus gen. et sp. nov., is
based on an exceptionally well-preserved, nearly
complete skeleton. This specimen represents the fifth dromaeosaurid
taxon recovered from the Upper Cretaceous
Djadokhta Formation and its laterally equivalent strata, which include
the Wulansuhai Formation, and adds to the known
diversity of Late Cretaceous dromaeosaurids. Linheraptor exquisitus
closely resembles the recently reported Tsaagan
mangas. Uniquely among dromaeosaurids, the two taxa share a large,
anteriorly located maxillary fenestra and a contact
between the jugal and the squamosal that excludes the postorbital from
the infratemporal fenestra. These features suggest
a sister-taxon relationship between L. exquisitus and T. mangas, which
indicates the presence of a unique dromaeosaurid
lineage in the Late Cretaceous of Asia. A number of cranial and dental
features seen in L. exquisitus and T. mangas, and
particularly some postcranial features of L. exquisitus, suggest that
these two taxa are probably intermediate in
systematic position between known basal and derived dromaeosaurids. The
discovery of Linheraptor exquisitus is thus
important for understanding the evolution of some salient features seen
in the derived dromaeosaurids.

Be careful: I first foudn this one
which is only a short version of the description of *Linheraptor*...
that I found curiously not in accordance with the ICZN... and for good
Plus, it was surprising given the presence of several veterans among the
authors of the paper...
Anyway, the holotype of *Linheraptor* is wonderful !! I say: more
dinosaurs founded on such skeletons !
PS: thank you, Yasmani Ceballos Izquierdo (being not a spanish speaker,
may I suppose Ceballos is part of your family name ?)
