New Papers With A Chance Of Meatballs

Hot on the heels of the last post, but stuff I learned about too late to

Salgado, L., and Coria, R.A. 2009. Barrosasaurus casamiquelai gen. et sp.
nov., a new titanosaur (Dinosauria, Sauropoda) from the Anacleto Formation
(Late Cretaceous: early Campanian) of Sierra Barrosa (Neuquén, Argentina).
Zootaxa 2222:1-16.

ABSTRACT: A new Late Cretaceous titanosaurian sauropod from the Sierra
Barrosa locality (Anacleto Formation, Late Cretaceous, early Campanian) of
Neuquén Province, Argentina, Barrosasaurus casamiquelai gen. et sp. nov., is
described. The holotype of this species consists of three large and
incomplete, although well-preserved, dorsal vertebrae (one probably the
third, the next the seventh or eighth, and the last the ninth or tenth). The
arrangement of neural arch laminae in the dorsal vertebrae of this
titanosaur differs from that present in other genera in the following ways:
the spinoprezygapophyseal laminae are well developed in the third vertebra,
and relictual in the seventh or eighth vertebra; two spinodiapophyseal
laminae are present in the seventh or eighth and in the ninth or tenth
vertebrae, the anterior spinodiapophyseal lamina being more strongly
developed than the posterior spinodiapophyseal lamina in the ninth or tenth
vertebra. These characters, among others, allow the recognition of this
individual as a new species of Titanosauria, which increases knowledge of
the diversity of titanosaurs in the Late Cretaceous of Patagonia.

Mateus, O., and Milàn, J. 2009. A diverse Upper Jurassic dinosaur ichnofauna
from central-west Portugal. Lethaia. doi: 10.1111/j.1502-3931.2009.00190.x.

ABSTRACT: A newly discovered dinosaur track-assemblage from the Upper
Jurassic Lourinhã Formation (Lusitanian Basin, central-west Portugal),
comprises medium- to large-sized sauropod tracks with well-preserved
impressions of soft tissue anatomy, stegosaur tracks and tracks from medium-
to large-sized theropods. The 400-m-thick Lourinhã Formation consists of
mostly aluvial sediments, deposited during the early rifting of the Atlantic
Ocean in the Kimmeridgian and Tithonian. The stratigraphic succession shows
several shifts between flood-plain mud and fluvial sands that favour
preservation and fossilization of tracks. The studied track-assemblage is
found preserved as natural casts on the underside of a thin bivalve-rich
carbonate bed near the Tithonian?Kimmeridgian boundary. The diversity of the
tracks from the new track assemblage is compared with similar faunas from
the Upper Jurassic of Asturias, Spain and the Middle Jurassic Yorkshire
Coast of England. The Portuguese record of Upper Jurassic dinosaur body
fossils show close similarity to the track fauna from the Lourinhã
