And now for a few more items of interest...
Kielan-Jaworowska, Z. 1998. Humeral torsion in multituberculate mammals.
Acta Palaeontologica Polonica, 43(1):131-134.
New finds from Mongolia confirm the presence of torsion in the humeri of
multis. Humeri are rare for multis and this new one for a new species of
Kryptobaatar confirm torsion at high levels and this suggests a sprawling
stance in disagreement with Serenoʼs argument for parasagittal posture more
similar to Didelphis.
Hurum, J.H. 1998. The braincase of two Late Cretaceous asian
multituburculates studied by serial sections. Acta Palaeontologica
Studied the braincases of Nemegtbataar gobiensis and Chulsanbataar vulgaris
from the Mongolian Late Cretaceous. Detailed braincase structure from sectioned
skulls with detailed cranial description.
Roger, J et al. (9 others). 1998. Paleoenvironmental and biotic changes
across the Cretaceous/Tertiary boundary in the Oman Mountains.
Bull. Society Geol. France, 1998(2):255-270. [In French].
Detailed description of foram faunas of the Late Cretaceous in the Oman Mtns.
New sites show a continuous section through the boundary. Various extinctions
before the boundary with recoveries and there is indeed the iridium layer as
well. Tectonically a very interesting area.
Coccioni, R. & S. Galeotti. 1998. What happened to small benthic
foraminifera at the Cretaceous/Tertiary boundary.
Bull. Society Geol. France, 1998(2):271-279.
Deep-water sections affected less than more shallow ones. After the event, the
ecosystem seemed to split into shallow-water epifaunal and
deep-water infaunal domains.
Lee, M.S.Y. 1998. Similarity, parsimony and conjectures of homology: the
chelonian shoulder girdle revisited. J. Evol. Biol., 11:379-387.
Detailed comparison, within the context of homology and phylogeny, of the
shoulder girdles of turtles as well as captorhinids, procolophonoids and
pareiasaurs. Part of a developing dialog between Lee and Rieppel.
This one looks interesting...
Arnold, E.N. 1998. Cranial kinesis in lizards. Pp. 323-357. In Hecht, M.K.,
R.J.MacIntyre & M.T. Clegg, eds. Evolutionary Biology, Volume 30.
Very detailed analysis within nice phylogenetic framework. To understand the
kinesis we see in dinos, itʼs good have another reptilian group experimenting
with it in detail. Nice.
Berman, D.S., A.C. Henrici & S.S. Sumida. 1998. Taxonomic status of the
Early Permian Helodectes paridens Cope (Diadectidae) with discussion
of occlusion of diadectid marginal dentitions. Annals of the Carnegie
Confirms that taxonʼs position of a diadectid through thorough prep of the
holotype. Discusses occulsal patterns in the form.
Hereʼs a neat one that should lead tomore data on paleoenvironments in
Podlaha, O.G., J. Mutterlose & J. Veizer. 1998. Preservation of δ18O and
δ13C in belemnite rostra from the Jurassic/Early Cretaceous
successions. American Journal of Science, 298:324-347.
And finally for now...
Maisch, M.W. & A. Hungerbuhler. 1997. Revision of Temnodontosaurus
nuertingensis (v. Huene, 1931), a large ichthyosaur from the Lower
Pliensbachian (Lower Jurassic) of Nurtingen, south western Germany.
Stuttgarter Beitrage zur Naturkunde, Ser. B, #248:11 p.
Confirm the validity and taxonomic status of this taxon, based on one
specimen originally named Leptopterygius but now shifted to T.
Thatʼs a wrap for now,
