Euro-dinosaur issue of Comptes Rendus Palevol
Euro-dinosaur issue of Comptes Rendus Palevol
From: Ben Creisler bh480@scn.org
The new issue of Comptes Rendus Palevol is available as in-
press on-line articles and has not been officially
published in paper form. However, it's an all Euro-
dinosaur issue and mentions a couple of new taxa:
Dromaeosauroides and Lusotitan. Here are the abstracts
with some additional info.
Godefroit, P. and F. Knoll (2003). Late Triassic dinosaur
teeth from southern Belgium.
Isolated Dinosaur teeth have been discovered in the Upper
Triassic locality of Habay-la-Vieille, in southern
Belgium. Ornithischia are represented by three dental
morphotypes; two of them closely resemble isolated teeth
from the Middle or Upper Jurassic of Portugal and England.
The presence of sauropods in the Upper Triassic of Europe
is confirmed. Sauropods already had a wide geographical
distribution during the Latest Triassic, as fossils have
been discovered in South Africa, Thailand and western
Europe. At Habay-la-Vieille, sauropods and prosauropods co-
existed at the end of the Triassic. Two dental morphotypes
may tentatively be referred to as theropod dinosaurs. The
study of isolated teeth indicates that dinosaurs were
already well diversified in the Latest Triassic of western
Europe. To cite this article: P. Godefroit, F. Knoll, C.

Bonde, Niels and Per Christiansen (2003) New dinosaurs
from Denmark
Only the Baltic island of Bornholm is likely ever to
produce Danish dinosaurs, not the western mainland
Denmark. The Mesozoic of Bornholm spans Late Triassic to
Late Cretaceous, with some potentially dinosaur producing
deposits from Early Jurassic to Early Cretaceous being
continental, lagoon, littoral or marginal marine. So far
the only dinosaurs have been found in 2000 and 2002 in the
basal Jydegaard Fm., carrying a `Purbeck-Wealden fauna' of
the Earliest Cretaceous (Late Berriasian or Ryazanian) at
Robbedale. Both are single tooth crowns; the first find, a
21-mm crown, is a dromaeosaurine, Dromaeosauroides
bornholmensis Christiansen & Bonde 2003, possibly the only
true dromaeosaur from the Lower Cretaceous of Europe.
Estimated length of the animal is over 3 m. The second
find is a somewhat unusual sauropod, most likely
titanosaurian, the crown being only ca 15 mm high, with an
unusual wear facet. Both teeth were derived from the
lowermost 2-3 metres of the formation. Future expectations
from this deposit are small ornithopods - and possibly
mammals. To cite this article: N. Bonde, P. Christiansen,

Allain, R. and Xabier Pereda Suberbiola (2003). Dinosaurs
of France
The French dinosaur record is one of the most extensive in
Europe; it ranges stratigraphically from the Late Triassic
to the Latest Cretaceous. All major clades of dinosaurs
but marginocephalians are known. About 20 species are
based on significant material; the theropods are the best
represented. Most of these taxa have been described or
revised in recent years. Important specimens have been
discovered in the Late Triassic of eastern France, the
Middle Jurassic of Normandy, and the Late Cretaceous of
Provence and Languedoc. The ichnological record is good
for the Late Triassic-Early Jurassic, and the Late
Cretaceous egg sites are among the richest in the world.

Dal Sasso, Cristiano (2003) Dinosaurs of Italy
In recent years, the idea that Italy was lacking dinosaurs
has been denied by a striking series of finds. Several
Triassic and Jurassic dinosaur tracksites were discovered
in the mid-eastern Alps, in particular within the Dolomia
Principale Fm. (Norian) and the Calcari Grigi Fm.
(Hettangian to Pliensbachian), while thousands of
Cretaceous (Santonian) prints came to light in Puglia
(southern Italy). Three skeletal remains are known so far;
they all belong to new, possibly endemic species that
evolved during Sinemurian (Saltrio theropod), Albian
(Scipionyx) and Santionian (Trieste hadrosaurs) times.
Both footprints and bony remains come from coastal
deposits and indicate a peculiar palaeobiogeographic
condition. The model of Bahamas-like small islands is no
longer consistent with the presence of large dinosaurs,
which could only survive in definitely terrestrial
ecosystems. As documented by the wide temporal range of
the dinosaur-bearing Italian outcrops, the Mesozoic
carbonate platforms of the Middle-Eastern Tethys might
have emerged several times, and quite extensively. To cite

Jagt, John W. M., Eric W. A. Mulder, Anne S. Schulp, Rudi
W. Dortangs and René H. B. Fraaije (2003) Dinosaurs from
the Maastrichtian-type area (southeastern Netherlands,
northeastern Belgium).
In comparison to pre-1980 records of nonavian dinosaur
remains from the Maastrichtian type strata, material
collected during the past 20 years is both fairly common
and diverse, consisting mostly of isolated cranial and
post-cranial remains of hadrosaurids. With the exception
of the type specimen of Megalosaurus bredai Seeley, a
fragmentary right femur, no theropod material is
represented in collections screened by us. In the present
contribution, specimens recognised in various collections
subsequent to our last tabulation (1999) are illustrated
and briefly discussed. Although we are fully aware that
the material is too limited to draw meaningful conclusions
from, the specimens are here tied-in with a preliminary
sequence-stratigraphic interpretation of the type
Maastrichtian, which is currently being refined by
strontium-isotope studies of coleoid cephalopods. To cite

Antunes, M. T. and Octávio Mateus (2003) Dinosaurs of
Portugal.
A synthesis on the state of art on dinosaur knowledge in
Portugal is presented. The following genera have been
recognized: Ceratosaurus, Torvosaurus, Lourinhanosaurus,
Allosaurus, cf. Compsognathus, Stokesosaurus, cf.
Richardoestesia, cf. Archaeopteryx, Euronychodon, cf.
Paronychodon, Dinheirosaurus, Lourinhasaurus, Lusotitan,
cf. Pleurocoelus, Lusitanosaurus, Dacentrurus, Dracopelta,
Phyllodon, Hypsilophodon, Alocodon, Trimucrodon, Draconyx,
Iguanodon, and Taveirosaurus. Most are from Late Jurassic
localities at the Lourinhã area and Guimarota. A new
genus, Lusotitan, is here raised to include the Late
Jurassic `Brachiosaurus' atalaiensis. Lower Cretaceous
until Cenomanian material is scarce, except for dinosaur
footprints. An interesting Late-Cretaceous, mostly small
dinosaur association has been collected between Aveiro and
Taveiro. To cite this article: M.T. Antunes, O. Mateus, C.

Lusotitan n. gen.
Etymology: from Luso, an inhabitant of Lusitania, an
ancient region that partly corresponds to Portugal; and
titan, the Greek word for a mythological giant.
Type species are given hereafter.
Lusotitan atalaiensis (Lapparent and Zbyszewski, 1957)
(Sauropoda: Brachiosauridae) [21].
Synonyms: Brachiosaurus atalaiensis Lapparent and
Zbyszewski, 1957.
Horizon: Late Jurassic, Tithonian, Sobral Unit.
Type locality: Peralta, near Atalaia (Municipality of
Lourinhã), west-central Portugal. Lectotype: Brachiosaurus
atalaiensis was based on several specimens, but the
authors never assigned the holotype specimen. Hence a
partial skeleton from Atalaia and isolated vertebrae from
Areia Branca, Porto Novo (Maceira), Alcobaça, Cambelas and
Praia das Almoinhas could be regarded as a syntype. Later
on, we designed here as lectotype the most complete
specimen (MIGM 4798, 4801-10, 4938, 4944, 4950, 4952,
4958, 4964-6, 4981-2, 4985, 8807, 8793-5; ), which is
composed of 28 vertebrae (two anterior cervicals, one mid-
dorsal, two neural arches, two caudal anterior centra, one
anterior caudal and an uninterrupted series of 18 caudal
vertebrae), 12 chevrons, fragmented ribs, a scapula(?)
distal epiphysis, two humeri, proximal left ulna, radius,
partial ilium, left ischium, left pubis, left tibia,
proximal end of right fibula and right astragalus. The
bone previously identified as a metacarpal II seems to be
a sacral rib.
Diagnosis: a Brachiosaurid, according to the humerus and
femur characters; mid-dorsals with very large pleurocoels;
anterior caudals have well-developed transverse processes;
midcaudal neural spine inclined almost vertically;
posterior caudal centra has convex anterior face; mid- and
posterior caudal centra are wider than high; slender
pelvis; notch at the posterodorsal margin of ilium;
postacetabular process of ilium bulky and without notch
between this process and the ischial peduncle; obturator
foramen of pubis closed; distal end of pubis
anteroposteriorly expanded; tibia bowed laterally;
proximal end of fibula is not rounded, but has an angular
outline.
Lusotitan is regarded as a Brachiosauridae due to the low
neural spines, prominent deltopectoral crest of the
humerus, elongated humerus, and the longitudinal axis of
the ilium is upward.
Grigorescu, Dan (2003) Dinosaurs of Romania.
The dinosaurs of Romania are exclusively Cretaceous.
Lowermost Cretaceous dinosaurs come from a bauxite mine in
the Bihor county (northwest Romania) that has yielded
thousands of disarticulated bones. Uppermost Cretaceous
dinosaurs have been known from the Ha eg Basin (south
Transylvania) since the end of the 19th century, mostly as
bone concentrations (`fossiliferous pockets'); more
recently, nests with dinosaur eggs, including hatchlings,
have been found in Hatzeg. Although separated by a ca 60
Myr gap, the two dinosaur faunas from Romania share some
common features: predominance of ornithopods, absence of
large theropods (substituted in the case of the
Maastrichtian Hatzeg assemblage by several small
theropods), and, in general, the small size of the
individuals (dwarfism). These aspects seem to be explained
by the isolated island habitat of both assemblages. To

Meyer, C. A. and B. Thüring (2003) Dinosaurs of
Switzerland.
Until 1960, the record of dinosaurs was rather poor in
Switzerland. Between 1960 and 1980, several new localities
with plateosaurid remains as well as prosauropod and
theropod tracks were found in Late Triassic sabkha and
floodplain environments. The discovery of large surfaces
with sauropod tracks in the Late Jurassic of the Jura
Mountains in 1987 triggered a stream of new data. More
than 20 new localities with tracks from both sauropod and
theropod dinosaurs in different stratigraphic levels have
been found since then. The latest discoveries include
trackways of iguanodontids from the Early Cretaceous of
the central Swiss Alps and a large Late Jurassic surface
with trackways of small sauropods in the northernmost part
of the Jura Mountains. The best skeletal record comes from
the Late Triassic, with scattered data from the Late
Jurassic. The track and trackway record appears to be best
in the Late Jurassic. To cite this article: C.A. Meyer, B.
