Highlights

An unusual turning sauropod trackway left by small trackmakers from
the Cretaceous China.
This trackway provides important constraints for the reconstruction of
locomotor features.
Two small-sized sauropod trackways are assigned to the Parabrontopodus
ichnotaxon.

Abstract

An unusual turning and a regular, straight sauropod trackway both left
by small trackmakers, as well as additional isolated medium-sized to
large sauropod tracks are described from the Early Cretaceous Dasheng
Group of the Zhucheng Basin, Shandong Province, China. Based mainly on
well-preserved tracks exhibiting three forwardly-directed digit/claw

Some recent news and blog items:

Interview with Heinrich Mallison at Tristan T. rex site in Montana (on
private land) (in German)

Found so far:

Dead T. rex buried when a river overflowed its banks and before body
could be scavenged, leaving bones relatively undamaged

Almost no remains of other animals found so far at the site (other
than crocodile teeth, fish scales), except piece of a Triceratops, and
fossil wood

Boring planned to check magnetic reversal signatures in the rocks

Latest Cretaceous dinosaur communities of southwestern Europe

Two new papers:

Bernat Vila, Albert G. Sellés & Stephen L. Brusatte (2015)
Diversity and faunal changes in the latest Cretaceous dinosaur
communities of southwestern Europe.
Cretaceous Research (advance online publication)
doi:10.1016/j.cretres.2015.07.003
http://www.sciencedirect.com/science/article/pii/S0195667115300264

Characterization of macroecological patterns for latest Cretaceous
dinosaur communities is essential to understand how those faunas were
changing during the run-up to the Cretaceous-Paleogene extinction
event, and thus the cause of the extinction. Outside of the
well-studied latest Cretaceous dinosaurs of North America,
southwestern Europe (France, Spain and Portugal) preserves one of the
richest end-Cretaceous dinosaur fossil records, as it has produced
hundreds of dinosaur fossil localities. We compiled a comprehensive
database of all dinosaur fossil occurrences from the uppermost
Cretaceous of the Ibero-Armorican region and analyze it statistically,
providing the first numerical study of the ecological and taxonomic
diversities of these communities. Our study corroborates previous work
that has identified a major faunal change in the latest Cretaceous
terrestrial vertebrate assemblages, and places this event around the
C31r-C31n reversal, in the early late Maastrichtian (c. 69 Ma).
Significant differences in ecological diversity metrics (dominance,
Shannon and Simpson) characterize the pre- and post-turnover
assemblages. The turnover event, therefore, did not only lead to a

Good day,

does anyone happen to have an astronomical paper of V. A. Hughes and D. 
Rutledge speculating about the supposed dinosaur-killing supernova? Partial 
citation is "Astronomical Journal, v.77, pp.210-214 (April 1972)", but I

Osteoderms of Montealtosuchus (Crocodyliformes), Upper Cretaceous of Bauru Basin, Brazil

A new paper:

Sandra Aparecida Simionato Tavares, Fresia Ricardi-Branco & Ismar de
Souza Carvalho (2015)
Osteoderms of Montealtosuchus arrudacamposi (Crocodyliformes,
Peirosauridae) from the Turonian-Santonian (Upper Cretaceous) of Bauru
Basin, Brazil.
Cretaceous Research 56: 651-661
doi:10.1016/j.cretres.2015.07.002
http://www.sciencedirect.com/science/article/pii/S0195667115300252?np=y

Highlights

The skin of Crocodyliformes contains osteoderms of various sizes and
shapes, that constitute a dermal shield.
A well-preserved dermal shield of Montealtosuchus arrudacamposi from
the Turonian-Santonian of Brazil is described.
The dermal shield of Montealtosuchus served for protection and
thermoregulation, allowing terrestrial locomotion.

Abstract

The skin of Crocodyliformes is characterized by osteoderms of various
sizes and shapes. It plays roles in defence, thermoregulation, sexual
attraction, calcium reserves, and locomotion. This study presents the
morphometric characteristics of osteoderms preserved in the nuchal,
dorsal, ventral and appendicular shield of Montealtosuchus

Theropod ziphodont serrated teeth, development and evolution (free pdf)

A new open access paper:

K. S. Brink, R. R. Reisz, A. R. H. LeBlanc, R. S. Chang, Y. C. Lee, C.
C. Chiang, T. Huang & D. C. Evans (2015)
Developmental and evolutionary novelty in the serrated teeth of
theropod dinosaurs.
Scientific Reports 5, Article number: 12338
doi:10.1038/srep12338
http://www.nature.com/srep/2015/150728/srep12338/full/srep12338.html

Tooth morphology and development can provide valuable insights into
the feeding behaviour and evolution of extinct organisms. The teeth of
Theropoda, the only clade of predominantly predatory dinosaurs, are
characterized by ziphodonty, the presence of serrations (denticles) on
their cutting edges. Known today only in varanid lizards, ziphodonty
is much more pervasive in the fossil record. Here we present the first
model for the development of ziphodont teeth in theropods through
histological, SEM, and SR-FTIR analyses, revealing that structures
previously hypothesized to prevent tooth breakage instead first
evolved to shape and maintain the characteristic denticles through the
life of the tooth. We show that this novel complex of dental
morphology and tissues characterizes Theropoda, with the exception of
species with modified feeding behaviours, suggesting that these
characters are important for facilitating the hypercarnivorous diet of
most theropods. This adaptation may have played an important role in
the initial radiation and subsequent success of theropods as
terrestrial apex predators.

The Ankylosauria is a group of herbivorous, quadrupedal, armoured
dinosaurs subdivided into at least two major clades, the
Ankylosauridae and the Nodosauridae. The most derived members of
Ankylosauridae had a unique tail club formed from modified, tightly
interlocking distal caudal vertebrae and enlarged osteoderms that
envelop the terminus of the tail. We review all known ankylosaurid
