MAASTRICHTIAN MARINE REPTILES, NEW VOLUME
Have done a quick search of the DML archives and the
following does not seem to have been mentioned, so here
we go. The following new volume arrived this week...
Mulder, E. W. A. 2003. _On Latest Cretaceous Tetrapods
from the Maastrichtian Type Area_. Publicaties van het
Natuurhistorisch Genootschap in Limburg, Reeks XLIV,
aflevering 1. Stichting Natuurpublicaties Limburg,
Maastricht, pp. 188.
Basically this volume is a collection of ten papers on the
Maastrichtian fossil tetrapods. If you have been collecting
all of Mulder's papers then none of this will be new (though
there are some updates and new information in some
sections), but given that most workers won't have access to
all of them, publishing all of them together is a good idea. It
also means that these papers are now easily accessible for
lay researchers and amateurs, many of whom may have
difficulties in getting hold of the technical literature. The
-- Prologue: Maastricht Cretaceous finds and Dutch
pioneers in vertebrate palaeontology. Mulder, E. W. A.
A historical review covering early interpretations of the first
mosasaur and Winkler's pioneering work on _Allopleuron_.
-- Pre-Maastrichtian tetrapods from the Maastricht area: the
oldest tylosaurine mosasaur (Reptilia: Squamata) from the
Late Cretaceous of Belgium; Hermann von Meyer (1860)
revisited. Mulder, E. W. A. & Mai, H.
First published in 1999, this revised version of that work is
a reanalysis of the Belgian mosasaur parietal described by
von Meyer in 1860. It is referable to _Hainosaurus_ and is
termed _Hainosaurus cf. bernardi_.
-- Comparative osteology, palaeocology and systematics of
the Late Cretaceous turtle _Allopleuron hofmanni_ (Gray
1831) from the Maastrichtian type area. Mulder, E. W. A.
This is the definitive work on _Allopleuron_, a chelonioid
probably close to the clade that includes _Syllomus_ and
extant cheloniines. With a rather flat carapace (recalling that
of extant _Natator_) and a surprisingly long tail, I think
_Allopleuron_ looks odd. It appears to have been restricted
to areas where sea grasses grew and conceivably co-evolved
with these plants.
-- Elasmosaur remains from the Maastrichtian type area, and
a review of the latest Cretaceous elasmosaurs (Reptilia,
Plesiosauria). Mulder, E. W. A., Bardet, N., Godefriot, P. &
Jagt, J. W. M.
This paper reviews global Maastrichtian elasmosaurid
occurrences. It is significant in showing that elasmosaurids
were 'still widespread and diversified during the late(st)
Maastrichtian' (p. 99).
-- Thoracosaurine vertebrae (Crocodylia: Crocodylidae)
from the Maastrichtian type area. Mulder, E. W. A.
Vertebrae referred to _Thoracosaurus_ are known from
Maastrichtian Belgium and suggest that thoracosaurines
could migrate between the coastal waters of NW Europe
and N. America by swimming across the narrow North
-- Dinosaur remains from the type Maastrichtian. Mulder, E.
W. A., Dortangs, R. W., Jagt, J. W. M., Jianu, J. W. M.,
Kuypers, M. M. M., Peeters, H. H. G., Schulp, A. S. &
Weishampel, D. B.
Assorted vertebrae, teeth, femora and other materials from
the Maastrichtian type area belong to indeterminate
hadrosaurids with the exception of _Megalosaurus bredai_.
What this is remains uncertain but, as noted in Chapter 10,
suggestions include ornithomimid (Russell 1972), abelisaur
(Le Loeuff 1992), and dryptosaur (Carpenter et al. 1997).
-- A large new mosasaur from the Upper Cretaceous of The
Netherlands. Dortangs, R. W., Schulp, A. S., Mulder, E. W.
A., Jagt, W. M., Peeters, H. H. G. de Graaf, D. Th.
This is the description of _Prognathodon saturator_, also
known technically as The Chunky Mother (joke). The type
specimen was scavenged by sharks. Dan Varner did the art.
-- Transatlantic latest Cretaceous mosasaurs (Reptilia:
Squamata) from the Maastrichtian type area and New
Jersey. Mulder, E. W. A.
Mulder argues that American _Mosaurus maximus_ is
conspecific with _M. hoffmanni_. This was initially
published in 1999 (check the DML archives if you need
-- On the alleged presence of _Halisaurus_ (Squamata,
Mosasauridae) in the latest Cretaceous of of the
Maastrichtian type area. Mulder, E. W. A.
Lingham-Soliar (1996) reported two _Halisaurus_ vertebrae
from Maastricht but without justifying this referral.
Examination shows that this referral cannot be supported
and they probably belong to _Plioplatecarpus marshi_.
-- Co-ossified vertebrae of mosasaurs and cetaceans:
implications for the mode of locomotion of extinct marine
reptiles. Mulder, E. W. A.
This is a reprinting of the paper of the same name from
_Paleobiology_ 27 (2001). Infectious spondylitis and
ligamentous ossification both occurred in mosasaurs. The
latter occurs also in whales and this offers strong support
for caudal-propelled locomotion in mosasaurs analogous to
that of cetaceans. Because _Plioplatecarpus_ exhibits these
vertebral fusions this is another nail in the coffin of
Lingham-Soliar's model of underwater flight for this taxon.
-- Stratigraphic distribution of Late Cretaceous marine and
terrestrial reptiles from the Maastrichtian type area. Mulder,
E. W. A., Jagt, W. M., Kuypers, M. M. M., Peeters, H. H.
G. & Rompen, P.
As it says, a review of stratigraphic distribution.
-- Epilogue: the Maastricht sea as a tetrapod habitat.
Mulder, E. W. A.
An overview of the palaeoecology and faunal diversity of
the Maastricht sea.
If you are into marine reptiles, or the fossils of the type
Maastrichtian, this volume is a must, even if you do already
own all of the papers reprinted here. Queries for ordering it
