Anabisetia published!
Okay, this isn't "new" news anymore, but I don't recall it being mentioned
onlist.
The reference is-
R.A. Coria & J.O. Calvo, (2002). A NEW IGUANODONTIAN ORNITHOPOD FROM
NEUQUEN BASIN, PATAGONIA, ARGENTINA. Journal of Vertebrate Paleontology
22(3): 503-509
"ABSTRACT?The discovery of a new iguanodontian ornithopod in the lower units
of the Neuquen Group (Rio Limay
Formation, early Upper Cretaceous) increases the South American record of
this kind of dinosaurs started few years
ago with the report of Gasparinisaura cincosaltensis. Anabisetia saldiviai,
gen. et sp. nov. is distinguished from all
other ornithopods by several features, as a flattened fifth metacarpal, a
scapula with a very strong acromial process,
and an ilium with preacetabular process longer than 50% of the total ilium
length. Anabisetia is more derived than
Tenontosaurus and shares with Euiguanodontia (Gasparinisaura 1 Dryomorpha)
the presence of one primary lateral
ridge on each maxillary tooth, a broad brevis-shelf and a reduced first
metatarsal. Derived features such as the transversely
flattened prepubic process and an anteroventrally oriented ischiadic foot
link Anabisetia with Dryomorpha (i.e.,
Dryosaurus, Camptosaurus and Iguanodon). Anabisetia strengths the hypothesis
that basal iguanodontian ornithopods
were present in South America before its with North America in the Late
Cretaceous."
Thanks to HP Mallon for helping me get this ref!
