dinosaur egg & sauropod tooth questions

[GUNTER.VANACKER@ELECTRABEL.COM]

I have 2 questions;


The much sought-after 15th volume of Gaia ("Aspects of Theropod
Paleobiology") contains following paper :

Loyal, R.S., D.M. Mohabey, A. Khosla & A. Sahni. Status and paleobiology of
the Late Cretaceous Indian theropods with description of a new theropod
eggshell oogenus and oospecies, Ellipsoolithus khedaensis, from the Lameta
Formation, District Kheda, Gujarat, western India. p379-387.

Could somebody (one of the happy few who have actual access to the Gaia
theropod volume) send me more details on the new oospecies Ellipsoolithus
khedaensis (size, surface ornamentation, eggshell thickness, oofamily, basic
eggshell type, resemblance to other egg types ...) ? This oospecies may be
interesting ... although there apparently are no associated embryonic
remains (which excludes referral to a particular dinosaur species), this new
oospecies could belong to the abelisaurid Indosuchus raptorius or a more
basal abelisauroid like Laevisuchus or Jubbulpuria (abelisauroids appear to
be the dominant theropods of the Lameta Formation). Ellipsoolithus could
thus be the first record of neoceratosaur eggshell, which would be crucial
in our understanding of theropod egg taxonomy.

I'm working on a project which goal is to make an inventory of all known
dinosaur egg oospecies, with details on their morphology, this will result
in an "egg cladogram" that will be compared to a recent dinosaur
phylogenetic study (based on skeletal evidence). My project will emphasize
on oogenera that can confidently be assigned to actual dinosaur genera. I
will also list undescribed eggshell remains that need urgent study.



My 2nd question (unrelated); 

Could somebody send me technical details on brachiosaurid teeth morphology
(and relative size) ?

Brachiosaurid teeth are described as "compressed cone-chisel-like", but how
do they compare to other sauropod teeth (like "spoon-like" in camarasaurids
or "peg-like" in diplodocids) ?
I'm looking for information on the teeth of "true brachiosaurids" like
Giraffatitan brancai and Cedarosaurus; apparently there are no teeth known
from Brachiosaurus altithorax. The large number of teeth referred to
Pleurocoelus or Astrodon may be less informative, since the taxonomic status
of these genera is uncertain.


Any information on the above 2 subjects can be forwarded off-list, or to the
DML if it's interesting to other dinosaur enthousiasts.


Thanks !
