New Refs #11



Some more refs, some new stuff, some from recent but older piles I just ran 
into:

First, one of the prettiest papers I have seen in a long time - the drawings 
are amazing.

Bjerring, Hans C. 1998. The fates of spiracular allostoses in mammals.       
Acta Zoologica, 79(1):51-67.

A detailed discussion of the phylogenetic origins of the upper and lower 
allostotic components that we now see in mammals. From fish through therapsids 
to mammals. Very detailed model analysis.


This came in late summer:

Jain, Sohan L. 1996. Aspects of vertebrate fossils from Pranhita -
   Godavari Valley  With emphasis on dinosaur localities. J.
   Paleontological Society of India, 41:1-16.

Nice summary of various terrestrial faunas from that region. Starts with the 
Middle Triassic which has fish, capitosaurs (Paratosuchus), dicynodonts 
(Wadiasaurus and Rechnisaurus), cynodont, rhychosaurs (Mesodapedon) and some 
suchians (protero and pseudo, undescribed taxa). The Late Triassic Maleri fm. 
Provides fish,  metoposaurs and chigutisaurs (amphibs), reptiles including a 
cynodont (Exaeretodon), rhychosaur (Paradapedon), the eosuchian Malerisaurus, 
the phytosaur
Parasuchus, a pseudosuchian (indet.), a coelurosaur Walkeria and a prosauropod 
with affinities to Massospondylus. The Dharmaran fauna is discussed briefly. It 
is Late Triassic and little known but apparently has a couple saurischians, a 
couple prosauropods, an ornithischian and sphenosuchid. The Kota fauna juts 
into the Early Jurassic and contains various fish, the dimorphodont 
Campylognathoides, the sauropod Barapasaurus and a batch o* symmetrodont 
mammals. There is also a quick note on Cretaceous dinos.

In case you missed it there is Paul*s view on the history of dinos:

Sereno, Paul C. 1997. The origin and evolution of dinosaurs. Annual
   Review of  Earth & Planetary Sciences, 25:435-489.

Too much to summarize here - its Paul*s summary.

And now an historical paper:

Taquet, P. & D. Contini. 1997. William Buckland et le *Megalosaure* de
   Franche-Comte nouvelles donnees historiques, stratigraphiques, et
   Paleogeographiques. Annales de Paleontologie (Vert-Invert),
   83(1):93-110.

Rediscovery of some bones originally examined by Buckland allows them
to be identified better to locality and taxon. Apparently they are from the
Callovian Puits de la Breme locality and the taxon appears to be related to
Strptospondylus and Eustreptospondylus.


A detailed summary of Robert Reisz*s opinion on the history of amniotes,

Reisz, Robert R. 1997. The origin and early evolutionary history of
   amniotes. Trends in Ecology and Evolution, 12(6):218-222.

Includes a nice phylogenetic diagram that starts with the Seymouriidae in the 
Carboniferous, goes up through the lepospondyles, Westlothiana and the 
diadectomorphs to the node Amniota. Here we branch to the Synapsida and the 
reptiles, first to the mesosaurs, the pareiasaur-turtle branch, and then on to 
the diapsids. He jumps the mesosaurs out at the Sauropsida node before the 
Reptilia node.


Next is a very detailed discussion of limb ossification patterns in 
ichthyosaurs.

Caldwell, M.W. 1997. Limb ossification patterns of the ichthyosaur
   Stenopterygius,  And a discussion of the proximal tarsal row of
   ichthyosaurs and other neodiapsid  Reptiles. Zoological Journal of the
   Linnean Society, 120(1):1-25.

As the title says...


Another paper on a too-little studied fauna,

Haycock, C.A., T.R. Mason & M.K. Watkeys. 1997. Early Triassic
   palaeoenvironments in the eastern Karoo Foreland Basin, South Africa.
   J. African Earth Sciences, 24(1/2):79-94.

Pre dinos but lots of neat beasts. Braided alluvial fan.


And finally, for today, a detailed study of the head of a Permian
temnospondyl.

Schoch, R.R. 1997. Cranial anatomy of the Permian temnospondyl
   Amphibian Zatrachys serratus Cope 1878, and the phylogenetic 
   Position of the Zatrachydidae. Neues Jahrbuch fur Geologie
   Palaontologie Abhandlungen, 206(2):223-248.

The z*a are probably a sister group to the dissorophoids.
