Hi Mike. Hope all is well with you. Time permitting, could you please
do me a favour and fwd the following to DML? Thanks for your help.
Jerry recently reported Jesper Milàn et al's new paper (in _Kaupia_ 14) on a
well-preserved sauropod manus track. Not only is this paper really interesting
in reporting vertical emplacement of the manus (this is apparently only present
in Upper Jurassic and Cretaceous tracks - not in older ones), Jesper et al.
also report the presence of 'rough tuberculate skin' on the manus. Not
mentioned to date here (AFAIK) is that this paper comes from a whole volume
devoted to vertebrate palaeontology - it's the symposium abstract volume for
the 3rd Annual meeting of the EAVP (European Association of Vertebrate
Palaeontologists). Below are the references (with comments where I can be
bothered) that concern Mesozoic reptiles - keep in mind that several of them
are just abstracts however. Dave Martill and I gave a presentation at the
meeting (systematics and ontogeny of _Tupuxuara_), but unfortunately our
abstract didn't make it into the volume.
Botfalvai, G. 2005. Bothremydidae indet. from the Upper Cretaceous of Hungary
(Csehbánya Formation). Kaupia 14, 71.
Two new skulls represent a new taxon close to _Foxemys_ (from the Maastrichtian
Buchy, M.-C., Vignaud, P., Frey, E. D., Stinnesbeck, W. & González, A. H. G.
2005. New occurrence of the genus _Geosaurus_ (Thalattosuchia, Crocodyliformes)
in the Tithonian (Upper Jurassic) of Mexico. _Kaupia_ 14, 72.
A new specimen - a juvenile or young adult despite its size - might represent a
new longirostrine taxon. It's similar in size to adults of _G. suevicus_, _G.
araucanensis_ and _G. vignaudi_, and much larger than _G. gracilis_.
Buffetaut, E., Escuillié, F. & Pohl, B. 2005. First theropod dinosaur from the
Maastrichtian phosphates of Morocco. _Kaupia_ 14, 3-8.
An isolated tooth appears to represent an abelisaurid with a body length of
7-8m. It's also argued here that - contrary to opinions from Novas and Sampson
et al. - the French Campanian-Maastrichtian material is indeed abelisaurid, and
new work in prep. supports this identification.
Canudo, J. I., Cruzado-Caballero, P. & Moreno-Azanza, M. 2005. Possible
theropod predation evidence in hadrosaurid dinosaurs from the Upper
Maastrichtian (Upper Cretaceous) of Arén (Huesca, Spain). _Kaupia_ 14, 9-13.
A pathological neural spine on a hadrosaur caudal vert bears fractures and a
growth suggestive of a healed theropod bite. The authors propose that the
swelling on the bone resulted from soft tissue infection, and they briefly
discuss the possibility of inoculation of microorganisms by way of a theropod
bite (cf. Komodo dragon).
Csiki, Z. & Grigorescu, D. 2005. A new theropod from Tustea: are there
oviraptorosaurs in the Upper Cretaceous of Europe? _Kaupia_ 14, 78.
An associated incomplete forelimb from the Hateg Basin is most like
_Chirostenotes_. Further evidence for caenagnathid-like taxa in the Cretaceous
of Europe? Incidentally, having examined cervical vertebrae of _Falcarius_
(literally alongside the holotype of _Thecocoelurus_), they are indeed highly
similar. However, the cervical vertebrae of _Chirostenotes_ are even more like
_Thecocoelurus_, so whether the latter is a basal member of the
_Therizinosaurus_ lineage*, or an oviraptorosaur as argued (Naish & Martill
2002, Naish et al. 2001), remains uncertain until we have more material.
* Clark et al. 2004 employed a node-based Therizinosauroidea which would
exclude _Falcarius_ and other basal taxa from this clade.

Martin, J. E. & Buffetaut, E. 2005. An overview of the Late Cretaceous
crocodilian assemblage from Cruzy, southern France. _Kaupia_ 14, 33-40.
This article discusses _Ischyrochampsa_, the alligatoroid _Acynodon_ and other
taxa, and reports a number of new, hitherto undescribed taxa.
Martin, T. 2005. Homoplasy in mammalian tribosphenic molars. _Kaupia_ 14, 88.
The oldest tribosphenic boreosphenidan - _Tribactonodon_ from the Wealden - is
younger than the oldest tribosphenic australosphenidan, Middle Jurassic
_Ambondro_. New information is present on _Asfaltomylos_, all of which has
since been published in JVP.

Dinosaur tracks from the Late Cretaceous Sabinas Basin (Mexico). _Kaupia_ 14,
A Maastrichtian site preserves theropod and pterosaur tracks; evenly spaced
parallel scratches might have been produced by a swimming pterosaur.

(Csehbánya Formation). _Kaupia_ 14, 93.
Fragmentary skull material (not belonging to _Allodaposuchus_ of the Hateg
Basin) represents one of the oldest alligatoroids.
Rauhut, O. W. M. 2005. Theropod dinosaurs from the Late Jurassic of Tendaguru,
Tanzania. _Kaupia_ 14, 94.
This abstract reports some of the material described in Rauhut (2005 - _Geol.
Mag._ 142, 97-107), but also provides new data derived from teeth. In the
(?Oxfordian-Kimmeridgian) Lower Saurian Beds there is evidence for one or two
large taxa; in the (Kimmeridgian) Middle Saurian Beds there appear to be two or
three large and two small to medium-sized taxa; and in the (Tithonian) Upper
Saurian Beds there is evidence for two or three large and two or three small to
medium-sized taxa. Some big teeth may belong to carcharodontosaurids, while
_Labrosaurus stechowi_ may indeed be ceratosaurid. Small teeth referred to
_Elaphrosaurus bambergi_ recall dromaeosaurine teeth, but this is doubtful and
there are also resemblances to the dentition of _Masiakasaurus_ (which is
obviously more in line with the evidence from postcranial remains).
Incidentally, as I've mentioned here and there a few times, there are a number
of vials of Tendaguru theropod teeth in the NHM collections - in the li!
Oliver's work these need looking at anew (of course, he may already have done
Rodriguez, J. C. 2005. Longbone histology of _Lirainosaurus astibiae_
(Sauropodomorpha: Titanosauria) from the Upper Campanian of Chera, Spain.
_Kaupia_ 14, 75.
New _Lirainosaurus_ material is reported from the Sierra Perenchiza Formation
of Valencia. Histological work indicates high growth rates throughout ontogeny,
with secondary osteogenesis resulting in dense Haversian bone. The latter might
have offered a biomechanical advantage as weight was increased.
Ruiz-Omeñaca, J. I., Canudo, J. I., Cruzado-Caballero, P., Infante, P. &
Moreno-Azanza, M. 2005. Baryonychine teeth (Theropoda: Spinosauridae) from the
Lower Cretaceous of La Cantalera (Josa, NE Spain). _Kaupia_ 14, 59-63.
Blesa Formation (Hauterivian-Barremian) baryonychine teeth are faceted on both
sides of the crown and thus differ from the teeth of _Baryonyx walkeri_ and
_Baryonyx_ sp (from the Isle of Wight) - they're therefore assigned to
Baryonychinae indet. Together with teeth from the Hauterivian Hastings Group
(England), these are the oldest reported baryonychine teeth. The article
includes a brief review of baryonychine distribution and taxonomy, and some
palaeobiological speculation: there are no fish at the La Cantalera site and
there may not have been standing bodies of water.

the type Maastrichtian. _Kaupia_ 14, 100.

girdle in sauropods. _Kaupia_ 14, 101.
The orientation of the scapula is examined and argued to stand at more than 50
degrees to the horizontal plane. For macronarians this makes the shoulder
region higher than usually thought, and also makes the CoG go further toward
the pelvis. This is only an abstract - no diagrams unfortunately. I would be
interested to know if the position reconstructed for the scapula matches the
rib facets reported by Parrish et al., and if this model allows for medially
braced clavicles (see Yates & Vasconcelos 2005).

& Tarubmuk, C. 2005. Description and comparison of sauropod remains discovered
in Ban Na Khrai, Kalasn Province (Lower Cretaceous of north-eastern Thailand.
_Kaupia_ 14, 104.
A new specimen of _Phuwiangosaurus_, discovered in 1998 and including a
braincase and other cranial elements, is reported from the Sao Khua Formation.

And while I'm here the following recently arrived.
Anderson, K. 2005. A new system of classifying bite marks on marine reptile
bones from the Oxford Clay, Peterborough. _The Quarterly Journal of the
Dinosaur Society_ 4 (3), 12-15, 28.
A system of classification recognises 18 different bite marks seen on marine
reptile bones (they include oblique indentation, deep plastic indentation,
incision, rotational impression, and bite-off). Some specimens preserve
multiple different types of bite mark: GLAHM V1840, a left humerus of a
_Cryptoclidus_, preserved nine different types! These include deep
indentations, shallow scratch marks and indentations as well as a bite-off
mark. The cryptoclidid seems to have been bitten by a _Liopleurodon_, and
either the prey or the predator was engaging in a twisting motion as the bite
was made. There is clearly plenty of evidence from Oxford Clay bones that
predatory taxa broke and damaged the bones of prey during attacks.
Forrest, R. 2005. The application of multivariate analysis in the
reconstruction of the skeleton of a specimen of _Muraenosaurus_ cf. _leedsi_.
_The Quarterly Journal of the Dinosaur Society_ 4 (3), 22-29.
The well preserved Oxford Clay plesiosaur G18.1996 - sat on the shelves since
1902 - represents an almost complete sequence of 75 vertebrae. Multivariate
analysis groups cervical vertebrae into three types, with the most caudal group
most resembling dorsal vertebrae. It is proposed that the novel locomotory
style employed by plesiosaurs explains their neck elongation: this works best
if the limb girdles are close together, and hence if the pectoral girdle is
moved caudally. This reduces manoeuvrability, and the solution may therefore
have been to increase neck length (while the necks are not that flexible, their
length does increase the size of the feeding envelope).
Liston, J. 2005. 'Clear as the difference between an arm and a leg?': a
reexamination of the Skye sauropod discoveries. _The Quarterly Journal of the
Dinosaur Society_ 4 (3), 18-21.
The Skye sauropod bone described by Clark et al. (1995), reported as a right
femur of _Cetiosaurus_ sp. (which probably means Eusauropoda indet), is in fact
a left humerus. This of course is reminiscent of the Skye coelophysoid tibia,
which was originally described upside down. A more technical version of the
contention presented in this article has since been published as.
Liston, J. 2004. A re-examination of a Middle Jurassic sauropod limb bone from
the Bathonian of the Isle of Skye. _Scottish Journal of Geology_ 40, 119-122.
Naish, D. 2005. The sauropod dinosaurs of the Wealden succession (Lower
Cretaceous) of southern England. _The Quarterly Journal of the Dinosaur
Society_ 4 (3), 8-11.
This article was submitted in 2001 and is now very dated. Discusses the
controversial presence of diplodocoids and camarasaurs in the Wealden (the
reference to _Aragosaurus_ as a camarasaur has of course since been outdated by
referral of that taxon to Titanosauriformes), as well as an early reference to
MIWG.7306 (later to become 'Europe's largest sauropod', aka 'Angloposeidon').
Better go. I have a wedding to attend.
