A new species of Palaeopython (Serpentes) and other extinct squamates from the Eocene of Dielsdorf (Zurich, Switzerland)

Georgalis, Georgios L. ; Scheyer, Torsten M.

In: Swiss Journal of Geosciences, 2019, vol. 112, no. 2, p. 383–417

The lizard and snake fauna from the late middle–late Eocene (MP 16–MP 20) of Dielsdorf, near Zurich, Switzerland, is described comprehensively in this paper. Detailed comparisons of the Dielsdorf material with other extinct taxa allow us to establish a new species of the large “booid” genus Palaeopython, i.e., Palaeopython helveticus sp. nov., characterized by a unique combination of...

Lizards and snakes from the late Miocene hominoid locality of Ravin de la Pluie (Axios Valley, Greece)

Georgalis, Georgios L. ; Rage, Jean-Claude ; Bonis, Louis de ; Koufos, George D.

In: Swiss Journal of Geosciences, 2018, vol. 111, no. 1–2, p. 169–181

We here describe lizards and snakes from the late Miocene (MN 10) of Ravin de la Pluie, near Thessaloniki, Greece, a locality widely known for its hominoid primate Ouranopithecus macedoniensis. The new finds comprise two large-sized lizards (a probable anguine and a varanid) and two snakes (an elapid and a small-sized “colubrine”). Even if the material is represented by few specimens,...

Fossil lizards and snakes from Ano Metochi – a diverse squamate fauna from the latest Miocene of northern Greece

Georgalis, Georgios L. ; Villa, Andrea ; Delfino, Massimo

In: Historical Biology, 2017, vol. 29, no. 6, p. 730–742

We here describe a new squamate fauna from the late Miocene (Messinian, MN 13) of Ano Metochi, northern Greece. The lizard fauna of Ano Metochi is here shown to be rather diverse, consisting of lacertids, anguids, and potential cordylids, while snakes are also abundant, consisting of scolecophidians, natricines and at least two different colubrines. If our identification is correct, the Ano...

Osteology, fossil record and palaeodiversity of the European lizards

Villa, Andrea ; Tschopp, Emanuel ; Georgalis, Georgios L. ; Delfino, Massimo

In: Amphibia-Reptilia, 2017, vol. 38, no. 1, p. 79–88

he capability of palaeontologists to identify fossil remains of a particular group of vertebrates strongly depends on the knowledge they have of its comparative osteology and on the actual presence of diagnostic differences among the considered taxa. This could have a relevant influence on the study of palaeodiversity, since a low recognisability causes a loss of data when trying to...
