And now for some more stuff...

Cifelli, R.L. & C. De Muizon. 1997. Dentition and jaw of Kokopellia
   juddi, a primitive marsupial or near-marsupial from the Medial
   Cretaceous of Utah. J. Mammalian Evolution, 4(4):241-258.

Cifelli, R.L. & C. De Muizon. 1997.Tooth eruption and replacement
   Pattern in early Marsupials. C.R. Acad. Sci., Earth & Planetary Sci.,
   326:215-220.

The former is a detailed description of new material for that taxon and
includes taxonomic/evolutionary implications. Suggests the common
ancestor of marsupials and placentals may be even more primitive than
currently thought. The latter is a short but detailed discussion of tooth
replacement and eruption in marsupials. Very unique and an
unambiguous synapomorphy for the Marsupialia. Typical quality
Cifelli stuff.

Onto turtles..

Chkhikvadze, V. & N. Amiranashvili. 1996. History of the fossil turtle
   studies in the Caucasus. Bull. Georgian Acad. Sci., 154(3):470-475.
   [In English]

Nice review of turtles from the Caucasus from Mesozoic to Tertiary. 
This just came in despite 1996 date.

Hirayama, R. 1998. Oldest known sea turtle. Nature, 392:705-708.

With comment,

Gee, Henry. 1998. The eyes have it. Nature, 392:651.

Santanachelys gaffneyi from the Santana formation, Early Cretaceous,
of Brazil. Rather nice and reposited in Chiba, Japan. The earliest known
sea turtle with a primitive paddle with workable digits but skull has
large interorbital foramina that should support huge lacrymal salt
glands. Clarifies the evolutionary progression to sea turtles.

Ji, Shu'an & Ji Qiang. 1997. Discovery of a new pterosaur in western
   Liaoning, China. Acta Geologica Sinica, 71(2):115-121. [In English]

New genus and species, Eosipterus yangi, with good bit of post cranial
material. Perhaps Early Cretaceous with a review of Chinese pterosaurs.
Appears to be a pterodactyloid.

Now for those into taphonomic stuff, this paper is on phosphatization
and fossilization and discusses new ostracodes but has implications for
some fossil vert material as well. Wish I read Russian.

Shkolnik, E.L. & E.I. Shornikov. 1998. Fast phosphatization of
   ostracodes and other organisms. Bull. Moscow Society of
   Naturalists, Geological Series, 73(1):47-56. [In Russian]


And now a theoretical paper... wish I read French.

Janvier, P. 1997. Phylogenetic classifications of living and
   fossil vertebrates. Bull. Soc. Zool. France, 122(4):341-354.
   [In French]

Detailed phylogenetic reconstructions and discussion of approaches
for whole Vertebrata. Might overwhelm those not heavily into
things phylogenetic and cladistic.

Not dinosaur but an interesting old beast a little better resolved...

Krajewski, C., L. Buckley & M. Westerman. 1997. DNA phylogeny
   Of the marsupial wolf resolved. Proc. Royal Society London,
   B, 264:911-917.

Problems with affinities of the Thylacinus, the marsupial wolf, with
two possible groups, the borhyaenids of South America or Australian
dasyuromorphians. DNA results support the latter with a late Oligocene
to early Miocene divergence. Still stuff to work out, however.

Bralower, T.J., C.K. Paull & R.M. Leckie. 1998. The Cretaceous -
   Tertiary boundary cocktail: Chicxulub impact triggers margin
   collapse and extensive sediment gravity flows. Geology,
   26(4):331-334 [April].

Cocktails of mixed faunas found result from massive sediment
gravity flows that jumbled up taxa of different ages together. 
Another marker unit related to the impact, found in the Gulf and
Carribean region.

That's enough for now,
