This first volume of the Proceedings of the 18th International
Senckenberg Conference (VI International Palaeontological Colloquium)
held in Weimar in April 20-25, 2004, consists of 25 individual
articles which deal principally with the European Late Cenozoic
(mostly, but not only) vertebrate palaeontology. A synthesis of
knowledge on the global Cenozoic palaeoenvironmental changes (ZACHOS
et al. 2001) as well as some present regional studies in North America
(GRAYSON 2006) and Southeast Asia (LOUYS et al. 2007) demonstrate
intriguing interactions between these changes and the evolution of
vertebrates, including perturbations in their diversity. RUDDIMAN
(2005) in his present book also addresses to the responses of the
terrestrial “Ice Age” fauna to the post-glacial global
warming. Moreover, we need clear imaginations on how the faunistic
evolution depends on environmental changes to predict and,
consequently, to avoid the further biodiversity loss. Therefore, such
a discussion of data as expected from this volume seems to be very
urgent.
This volume starts with Foreword, Preface, and an introductory paper
entitled Deer, Pleistocene interregional correlations, Linear Pottery
Culture and East- West mediation - 80th birthday of HANS-DIETRICH
KAHLKE (by H. HEMMER). The latter is addressed to the biography of the
famous German specialist, who made the greatest efforts in the
Quaternary vertebrate palaeontology. The further papers deal each with
its specific subject.
SOTNIKOVA describes a find of Nurocyon chonokhariensis gen. et
sp. nov. in the Lower Pliocene lacustrine deposits of northwestern
Mongolia. This species demonstrates sharp differences from the other
Canini, and it is considered as a representative of their separate
lineage. SARDELLA discusses briefly the evolution of the Eurasian
Pliocene-Pleistocene jaguars with the data collected at the Monte
Argentario locality in Italy. The presence of leopard remains at this
locality is not confirmed. VAN ESSEN et al. address to the
“Cryptomastodon problem“. A detailed examination of the supernumerary
teeth of proboscideans, subdivided into three categories, is given,
and the presence of Stegodon trigonocephalus MARTIN, 1887 in the
Pleistocene of Java is argued. DENG presents a good synthesis on the
Neogene rhinoceroses from the Cenozoic strata of the Linxia Basin in
China. Besides a detailed taxonomic synopsis, five stages in the
regional evolution of the mentioned group are recognized. Another good
feature of this paper is all fossil finds are justified
stratigraphically. The earliest record of the woolly rhino is pointed
out. The reviewer is just curious, why did this woolly animal
appeared at that time, and why in Gansu? Perhaps these questions are
explained in the other article by DENG &DOWNS (2002), but to present
some brief remarks in the current paper would be not less
important. LACOMBAT continues the discussion on this topic, and his
paper deals with the European Pleistocene rhinoceroses. Four studied
species demonstrate intriguing changes in their sizes through time. It
is possible to agree with the author, that such changes can be useful
for the biostratigraphical developments. EISENMANN suggests against
the early separation of the caballine branch of Equids, i.e., against
the biomolecular interpretations. The “Sussemiones“, which were
descendants of Caballines, wide spread over the continents in the
Pliocene446 Paläontologie allgem. Pleistocene. They went to be
extinct together with the rise of the Caballines. The author
hypothesizes that the extant equids appeared simultaneously somewhen
in the early Middle Pleistocene. It would be intriguing to know,
whether there was any environmental control of events recorded in the
evolution of this fossil group. CROITOR gives a taxonomic synthesis on
the Pleistocene cervid genus Praemegaceros PORTIS, 1920. Three
parallel lineages, namely Praemegaceros, Orthogonoceros and
Neoleipoceros are framed herein as subgenera. Changes in humidity was
an important force of cervid evolution and migrations. VAN DER MADE
analyses the evolution of the Pleistocene giant deer Megaloceros
giganteus, which populated a large territory of Northern Eurasia. The
original population of this taxon was divided into two particular
subgroups, lived in Western Europe and Eastern Europe- Western Asia
respectively. They differed by the robusticity of limb bones. The
Western European population went to be extinct around 20 Ka, and
Western Europe was re-populated by the Eastern European population
around 13 Ka. The author hypothesizes only little changes in body
weigth during the entire evolution of this species. VAN DER GEER et
al. describe the endemic Pleistocene deer Candiacervus sp. II from
Liko Cave of Crete. A skeleton of this taxon was mounted. It is noted
that this animal might have occupied a niche of goat-like bovids in
the rocky environment.
CRÉGUT-BONNOURE et al. provide a taxonomic synopsis on the Late
Cenozoic Caprinae, included Ovibovini, Ovini and Caprini. Their
morphological and metrical characters are summarized. Diversity of
Caprinae rose from the Pliocene by the end of the Early
Pleistocene. The beginning of the Middle Pleistocene is characterized
by a climatically-induced turnover, when the earlier-existed taxa
disappeared. Further immigration supported the diversity
rise. BUKHSIANIDZE & VEKUA describe a new fossil, i.e. Capra dalii
nov. sp., which was found in the Upper Villafranchian strata at the
Dmanisi Locality in East Georgia. This fossil occurs together with the
human remains, and former is linked phylogenetically with the
Caucasian turs. TAKKEN BEIJERSBERGEN deals with the genus Lemmus. Its
Middle Pleistocene representatives from Schöningen (Germany) and
Boxgrove (UK) localities allow to conclude a more complicated history
of lemmings than imagined previously. An important evolutionary event
(it is not clear enough of what kind) is hypothesized to have occurred
at the end of the Pleistocene. MARCOLINI et al. present some
interesting conclusions from their studies of the morphological
variability in the first lower molars of Ogmodontomys from the
Early-Middle Pliocene of the Meade Basin (U.S.A.). An application of
Fourier Analysis permitted to recognize the occurrence two species,
namely O. sawrockensis and O. poaphagus.
MASINI&ABBAZZI review a record of the small mammals of Italy. The
authors measured some abundance and diversity patterns, which are well
justified against the available biostratigraphic framework. The
factors controlled the number of sites (both open environment and
cavity environment sites are considered) are sampling and preservation
biases, and the “environmental preferences of owls”. The regional
taxonomic diversity of small mammals changed significantly during the
Pliocene-Pleistocene. It is concluded that only the Toringian (late
Middle-Late Pleistocene) diversity is estimated correctly, whereas the
diversity of the earlier Lehrbücher, zusammenf. Darstellungen,
Bibliographien 447 time intervals is underestimated. In fact, this
article is a true pearl of the reviewing volume, and it gives us an
example of how to deal with the measurements of the mammalian fossil
record. The reviewer just would like to suggest more carefully work
with those diversity estimations, which involve calculations per
absolute time units. 1 Ka in the Pliocene and 1 Ka in the Holocene
bring a different “quantity” of information on the changes in the
geosphere, and, consequently, they are incomparable. PALOMBO &
GIOVINAZZO discuss the cenogram analysis, which deals with the body
mass distribution in the ancient faunas, with the data from the Late
Cenozoic of Italy. Although this method provides some uncertainties,
it seems to be a useful tool to evaluate the changes in local
humidity. FRANZEN addresses his paper to the mammalian and
palaeoenvironmental records in the Mainz Basin. An examination of
available (very rich!) fossil localities permitted to establish the
interrelations between the palaeoecosystems, sedimentation, tectonics,
and taphonomic processes. Fig. 4 (p. 240) illustrates, in particular,
the regional Oligocene- Miocene changes in salinity. Fig. 9a and 9b
(p. 243-244) document faunal turnover in the middle Vallesian-early
Turolian at two important localities, namely Eppelsheim and
Dorn-Dürkheim. The formation of the Rhine River Canyon is explained by
the overflow of the earlier existed lake at about 800 Ka. NADACHOWSKI
et al. present a review of the Pliocene vertebrate localities of
Moldova. The recognized Moldavian Faunal Complex is brought in
correspondence with the Ruscinian (MN 15). The presence of MN16a and
MN17-Q1 assemblages is also established. All localities are described
in a single manner, and they are accompanied by detailed taxonomic
lists, illustrations of the most intriguing fossil remains, and also
by a pretty lithologic sections, which together make this paper very
important. The authors emphasize on the bird remains. SABOL et
al. provide new knowledge on the early Late Pliocene Hajnáka I site
in Southern Slovakia, where MN16a assemblage is established. The
evolution of local ecosystems was linked with the volcanism. The
mammalian assemblage was dominated by forest taxa like tapirs,
mastodons, rhinoceroses, and cervids, whereas open-land and aquatic as
well as semi-aquatic taxa make only 37% of this assemblage. The strong
feature of this paper is a successful integration of palaeobotanical
and palaeozoological data. DELSON et al. give a detailed
characteristics of the Senèze Locality in France, whose age is
evaluated as a Late Villafranchian, although such dating is debated.
34 mammalian species, which include representatives of Primates,
Proboscidea, Perissodactyla, Artiodactyla, Carnivora, Lagomorpha and
Rodentia, several taxa of birds, Anapsida, Amphibia, Actinopterygii,
Mollusca and Crustaceamorpha as well as palynological data make an
exceptional fossil record. Important are the present finds of
Dicerorhinus etruscus etruscus (FALCONER, 1859), Eucladoceros
ctenoides ctenoides (NESTI, 1841) and Acinonyx pardinensis (CROIZET &
JOBERT, 1828).
VAN DEN HOEK OSTENDE & DE VOS summarize a knowledge on the Tegelen
locality in Netherlands. This site is explored for about a century,
and many remains of fishes, amphibians, reptilians, birds, mammals
(Soricomorpha, Rodentia, Lagomorpha, Chiroptera, Primates,
Proboscidea, Artiodactyla, Perissodactyla and Carnivora) have been
found there. However, the lack of good excavations and complicated
taphonomic patterns do not permit to make a clear decision on the age
of the Tegelen fauna. The authors hypothesize a “mixture of ages”.
O’REAGAN et al. evaluate the possibilities of the early hominin
movements with the mammalian migrations. Analyses of modern
biogeographic patterns, phylogeography (based on mitochondrial DNA
analyses), and palaeobiogeography permit to favour the dispersal route
through the Levantine Corridor, whereas dispersal across Gibraltar
appears unlikely. MAZZA documents responses of the Late Cenozoic
evolution of the Italian large land mammals to the environmental
changes. Decline in temperature and humidity caused drops in primary
productivity and replacement of smaller browsing taxa by gregarious
taxa and of carnivores by social predators. An expansion of steppes
since 0.9 Ma provoked a major turnover in faunistic communities as
well as an increase in biodiversity and biomass. Alternatively, an
expansion of woodlands at the end of the Last Glacial led to the
decline in both plant and animal communities. This paper is
undoubtedly an important contribution. However, it would be better if
to present the changes both in diversity and climate not
qualitatively, but at least semi-quantitatively. All conclusions are
very important, and, therefore, they should be strongly supported by
the numerical calculations.
SALA & MARCHETTI discuss briefly the importantce of the Po Valley
floodplain for the connection of south-western and central-eastern
Europe, which were zoogeographically distinct regions. The so-called
Central Slovenian Corridor functioned since the Middle Pleistocene,
but it was unavailable in the Pliocene and Early Pleistocene. PALOMBO
et al. attempt a careful analysis of similarity between the
Pliocene-Middle Pleistocene large mammalian communities of Southern
Europe. A total of 286 taxa are considered. The similarity was
evaluated quantitatively with the Jaccard Coefficient and cluster
analysis. Two clusters have been established, namely the
Pliocene-early (pre-Jaramillo) Early Pleistocene and the late Early-
Middle Pleistocene. A significant gap between them marks a transition
from Villafranchian to Galerian faunas. Some other faunal renewals are
also reported. All of them were evidently resulted from the climatic
changes. Somewhat strange happened on the Fig. 2b (p. 335), which
illustrates fossil localities in Eastern Europe. Eight sites (numbered
as 42-44, 46-48, 50 and 54) are listed as Russian. But they are
evidently located in southwest Ukraine and possibly Moldova! Inspite
of explanations in the text, such uncertainty on figure may bring a
confusion for those, who will operate with this very important paper.
All information presented in this volume is, undoubtedly, of great
interest. A large number of taxa are described and
illustrated. Besides to give taxonomic descriptions, four tasks
(numbered below) would be solved in this volume as one may conclude
from its whole title. This edition presents a good illustration of the
vertebrate fossil heritage of Europe. However, just few articles are
directly addressed to biodiversity and its particular patterns
(1). The questions considered diversity changes, rates of origination
and extinction are discussed only occasionally. A good example of a
paper, which is addressed to palaeobiological matters, is that of
MASINI & ABBAZZI. However, taxonomic palaeontology stays at the first
plan in the whole volume, and, thus, specialists in the palaeobiology,
i.e., those who are specialized in fossil diversity changes and mass
extinctions, may be slightly disappointed reading it. Evolutionary
processes (2) are better considered as well as palaeoenvironmental
context (3). However, the reviewer would like to note the Lehrbücher,
zusammenf. Darstellungen, Bibliographien 449 lack of appropriate
number of palaeogeographical and even palaeobiogeographical maps, and
a little amount of figures, which will precisely illustrate the
palaeoenvironmental changes. Available palaeonvironmental remarks
often sound too general. Interregional correlations (4) are considered
widely in this volume, and, particularly, in a review paper by PALOMBO
et al. As a whole, such syntheses as those published by GRAYSON (2006)
and LOUYS et al. (2007) would benefit these proceedings. But as it
becomes clear from the Preface, more synthetic papers will be included
into the second volume of the proceedings. On the reviewer’s opinion,
this is an interesting volume, which presents many new and important
results, and it will be of interest for the specialists in the Late
Cenozoic vertebrate palaeontology.
