Non, ce n'est pas une insulte en polonais ...
C'est le nom (à coucher dehors avec un billet de logement) d'un archosaure très très grand tout nouvellement décrit ...
Abstract:
"Systematic Paleontology
Archosauromorpha Huene, 1946
Archosauriformes Gauthier, Kluge & Rowe, 1988
Archosauria Cope, 1869 sensu Gauthier, 1986
_Razanandrongobe sakalavae_, gen. et sp. nov.
Holotype: MSNM V5770 Fragmentary right maxilla bearing three unerupted
teeth.
Referred material: MSNM V5771-5777, isolated teeth.
Etymology: _Razanandrongobe_, Malagasy composite name for ancestor
(Razana-) of the large (-be) lizard (-androngo-); sakalavae, Latin for
of Sakalava, the ethnic group that inhabits the Mahajanga region.
Diagnosis: large predatory archosaur with deep, robust maxilla bearing a
prominent maxillary medial shelf; thecodont tooth implantation; alveolar
channels nearly straight in the sagittal plane; alveoli (as preserved)
sub-rectangular in ventral view; fused interdental plates with a surface
texture consisting of marked ridges and furrows extending for a short
distance also above the dorsal margin of the interdental plates; heterodont
dentition; incisiform rostral teeth, U-shaped in cross-section; stout
lateral teeth, sub-oval in cross-section; smallest lateral teeth,
globe-shaped; denticles present on both carinae in all the teeth, and very
large (0.8- 1.4 per mm) (unambiguous autapomorphy of the taxon)."
The paper goes on to say that _Razanandrongobe_ is either a crocodylomorph
or a theropod ("Although _R. sakalavae_ differs in some aspects from any
currently known member of the Crocodylomorpha and Theropoda, it belongs
certainly to one of those two taxa.") The preserved maxillary fragment is
192 mm long, 124 mm high, and 96 mm wide, and the authors suggest that
_Razanandrongobe_ might have been of a similar size to either _Sarcosuchus_
(if a crocodylomorph) or _Daspletosaurus_ (if a theropod). In other words,
pretty darn big either way. _Razanandrongobe_ was clearly a carnivore, with
the teething show some similarities to those of tyrannosaurids (but not
enough to indicate a close phylogenetic relationship, just a similar mode of
predatory behavior), and indicating it could chomp on bone and tendons.
_Razanandrongobe_ may have fed on sympatric sauropods such as
_Lapparentosaurus_ and _Archaeodontosaurus_, say the authors.
