Just received...



These just showed up in the mail today.  I don't think that they have been
posted yet:

Brinkman, D.L., R.L. Cifelli & N.J. Czaplewski. 1998.  First occurrence of
_Deinonychus antirrhopus_ (Dinosauria: Theropoda) from the Antlers Formation
(Lower Cretaceous: Aptian-Albian) of Oklahoma.  Oklahoma Geological Survey
Bulletin 146: 1-27.

Reports on the partial skeleton of a subadult specimen of _Deinonychus_
(associated with _Tenontosaurus_ remains). Some new elements, such as the
occipital region.

Watabe. M., Ya. Ariuinchimeg & D. Brinkman.  1997.  Dinosaur egg nests and
their sedimentary environments in Bayn Shire locality (Late Cretaceous),
Eastern Gobi.  Abstract of Report Meeting Mongolia-Japan Joint
Paleontological Expedition, Mongolian Paleontological Center, Ulan Bator,
Mongolia.  June, 1997.

Three different egg types collected: large and elongated (?large theropods);
medium-sized spherical-to-ellipsoid (hadrosaurs or sauropods?); small and
very thin-shelled (?small theropods).

Hicks, J. & D. Brinkman. 1997.  Preliminary paleomagnetic results from the
Cretaceous of the Eastern Gobi, Mongolia.  Abstract of Report Meeting
Mongolia-Japan Joint Paleontological Expedition, Mongolian Paleontological
Center, Ulan Bator, Mongolia.  June, 1997.

Paleomag results for the Khuren Dukh locality of the Dzun Bayan Fm., and the
Bayn Shire and Burkhant localities of the Bayn Shire Fm.  All normal
polarity.  Probably somewhere within normal polarity chron 34 (the
Cretaceous Long Normal, 118-83 Ma).  Note that because the early Campanian
was a reversed polarity time, this strongly suggests (contra some earlier
thoughts) that the Bayn Shire does NOT extend into the Campanian, but was
somewhere in the Cenomanian-Santonian.  (So, time to go fix the age ranges
for _Alectrosaurus_ & company...).


P.S.:  Thanks Dan!!
