Here are some new papers from the last issue of the Journal of Paleontology,
possibly of interest to some even though not directly dinosaur-related...
Nydam, Randall L., Jeffrey G. Eaton and Julia Sankey, 2007: New taxa of
transversely-toothed lizards (Squamata: Scincomorpha) and new information on
evolutionary history of "teiids". Journal of Paleontology 81 (3), pp. 538-549
Abstract: New material of polyglyphanodontine lizards from the Late
Cretaceous has been found in various localities in western North America.
transversely oriented teeth representing a new species of Dicothodon were
recovered from the Turonian of southern Utah. These specimens necessitate
reassignment of Polyglyphanodon bajaensis to Dicothodon (Polyglyphanodon)
>From the Campanian of Utah, additional teeth and jaw fragments referable to
Manangysaurus saueri have been recovered and this
species is reassigned here to Peneteius (Manangysaurus) saueri. Also, an
isolated tooth referable to Peneteius has been recovered from the Campanian of
southern Texas. The results of a phylogenetic analysis support a monophyletic
grouping of the transversely-toothed taxa with Bicuspidon as the sister taxon
of Polyglyphanodontini new taxon, which is comprised of Polyglyphanodon,
Peneteius. The phylogenetic analysis also places ââteiidââ lizards
the Cretaceous of Asia and North America in a monophyletic group,
Borioteiioidea new taxon, which is the sister taxon to the Teiioidea (Teiidae
Gymnophthalmidae). This new hypothesis of the interrelationships of these taxa
the reevaluation of several characteristics that were previously considered
diagnostic for a more
inclusive Teiidae. Another implication of our results is that Teiidae (sensu
stricto) has no demonstrable pre-Tertiary occurrence. It appears that
Teiioidea and Borioteiioidea diverged from a common ancestor by the Early
Cretaceous. The Teiioidea entered South America and are currently represented
Teiidae and Gymnophthalmidae, whereas Borioteiioidea radiated throughout North
America with subsequent dispersal to Asia and Europe.
Peppe, Daniel J., Erickson, J. Mark, and Leo J. Hickey, 2007: Fossil leaf
species from the Fox Hills Formation (Upper Cretaceous: North Dakota, USA) and
their paleogeographic significance. Journal of Paleontology 81 (3), pp.
Abstract: Seven fossil leaf species are described from impression fossils
collected from the Upper Cretaceous (Maastrichtian) Fox Hills Formation in
south-central North Dakota, USA. They are Marmarthia johnsonii n. sp.,
Nilssoniocladus yukonensis n. comb., Nilssoniocladus comtula n. comb.,
borealis, Rhamnus salicifolius, Paloreodoxites plicatus, and Zingiberopsis
magnifolia. These species represent some of the elements of the Fox Hills
that have paleogeographic ranges to the northwest (N. yukonensis, N. comtula,
and M. borealis) and to the southwest (M. johnsonii, R. salicifolius, P.
plicatus, and Z. magnifolia) of the Fox Hills type area. The identification
reappraisal of these species represent an effort to understand the
relationships of Late Cretaceous floras across the Northern Hemisphere.
