and Franco-Rosas, 2001. Scanning electron microscope analysis on
Maniraptoriformes teeth from the Upper Cretaceous of Southeastern Brazil. JVP
21(3) 33A. Over
two-hundred teeth from the Bauru Group (Adamantina and Marilia Formations) of
Brazil were examined and found to belong to dromaeosaurids (including
velociraptorines), troodontids, Richardoestesia gilmorei and four new taxonomic
groups. Now
that sounds promising... Gishlick,
2001. Evidence for muscular control of avian style automatic extension and
flexion of the manus in the forearm of maniraptors. JVP 21(3) 54A. Three
muscles are involved with the coordinated folding of the forearm and
metacarpus in birds- m. extensor metacarpi radialis (EMR), m. flexor metacarpi
ulnaris (FMU) and m. extensor metacarpi ulnaris (EMU). These insert in a
particular way in birds to allow "two joint" muscles that can
automatically flex and extend. Caudipteryx, Deinonychus, Velociraptor and
Archaeopteryx are shown to have osteological correlates for these insertions,
showing they had an avian-like wing-folding mechanism. Did
they mention something that does not have the... character? :-) Leshchinskiy,

Cretaceous vertebrate locality Shestakovo, Western Siberia, Russia: A refugium
for Jurassic relicts? JVP 21(3) 73A. The
title refers to the fact that tritylodontid almost-mammals have been identified
from there. Before the discovery of EK tritylodontids in Japan in IIRC 1998
tritylodontids were supposed to have died out in the MJ. Here’s a
list of EC tritylodonts Genus: Xenocretosuchus TATARINOV & MATCHENKO,

xenos, “Foregin”, Latin, cretaceous, “Cretaceous”, and Greek, suchus,
