 There are a few interesting items to talk about:

Dave Weishampel has a nice review of the Fraser & Sues volume in
the current issue of Nature (20APRIL95) 374:685.

Barret & Upchurch redescribe the type material of Regnosaurus northamptoni,
which isn't much - a partial right mandible - which was collected and
originally described by Mantell in 1838 and has been assigned at various
times to Iguanodon, the ankylosaurs and the sauropods. The authors suggest
instead that it is a stegosaur with affinities with Huayangosaurus based
on two shared characters. They then do some discussion of the ramifications
for stegosaurian phylogeny - suggest R.n. and H. are sister taxa that form
a nice outgroup for the rest of the stegosaurs, including Dacentrurus.

    stegosaurian dinosaur from the Lower Cretaceous of southern England.
    Geol. Mag. 132(2):213-222.

A neat article on the environment of the Solnhofen limestone (the
nature of the lagoon and its sediments):

Milsom, C. & T. Sharpe. 1995. Jurassic lagoon: salt or soup?
   Geology Today  Jan-Feb 1995 p. 22-26.

And a note there on the Wiltshire pliosaur on pages 6-7.

A neat book on the marsupial radiations with a nice discussion of
paleobiogeography - with Mesozoic discussions - in chapter 9.

Szalay, F.S. 1994. Evolutionary History of the Marsupials and an
    Analysis of osteological characters. Cambridge U Press, 481 p.

The recent Palaeontology is a big group of fossil tetrapod papers.
Rieppel has one paper on a a middle Triassic nothosaur from Germany,
a new Lower Cretaceous pterodactyloid from texas (Lee), a redescription
of an ichthyosaur from Yorkshire that was swordfish like by the ever
elegant Chris McGowan, and a Callovian plesiosaur skull from the UK
(Brown & Cruikshank). By the way, if you want to see some beautiful
Cretaceous dragonflies see the paper by Nel & Escuille.

   of Brazil. Palaeontology 37(4):923-930.

   plesiosaur Cryptoclidus eurymerus, and the suaropterygian cheek.

   juvenilis from the middle Triassic of Germany. Palaeontology 37(4):733-745.

Finally, 2 papers from Geology on K-T stuff. The first suggests that the
faunal changes that took place in the planktonic foram assemblages started
before the impact (uh-oh they must be insane!) ;-)

Langoria, J.F. & M.A. Gamper. 1995. Planktonic formainiferal faunas across
   the Cretaceous-Tertiary succession of Mexico: implication for the
   Cretaceous-Tertiary boundary problem. Geology 23(4):329-332.

and a new discussion that talks about osmium and strontium isotopes that
strongly support an impact and tsunami origin rather than volcanic origin
(whew, sanity again)   ;-)

Meisel, T., U. Krahenbuhl & M.A. Nazarov. 1995. Combined osmium and
   strontium isotopic study of the Cretaceous-Tertiary boundary at Sumbar,
   Turkmenistan: a test for an impact vs. a volcanic hypothesis.

That's enough for now. Ralph Chapman, NMNH
