Taxonomic and stratigraphic problems of the family Tmetoceratidae and the genera Dumortieria, Catulloceras, Cotteswoldia, Pleydellia and Tmetoceras included in it are briefly discussed. Fifteen species of Tmetoceratidae are described and illustrated from the Upper Toarcian-Aalenian ammonite assemblages of the Gerecse Mts (NE Transdanubian Range, Hungary). The fauna described here is closely allied to the Mediterranean Province of the Mediterranean-Caucasian Realm.
The excellently preserved toad fossil was found the Middle Miocene (Badenian) lower freshwater-brackish diatomite layers in Szurdokpüspöki, Mátra Mountains, northern Hungary. This is the first amphibian fossil of the locality. This specimen is the only toad skeleton from Hungary and possibly from the Miocene of Europe. The toothless premaxilla and maxilla denote the family Bufonidae and the ossification of the frontoparietal, prootic and exooccipital indicates the toad species Bufo viridis. The difference from other bufonid toads is the presence of a small bulge on the ventral side of the well-preserved right ilium; thus it is referred to as Bufo aff. viridis. The size of the bones of the fossil anura suggests it was probably a young specimen. Detailed taxonomic description is given.
encountered Upper Cretaceous (Santonian) Iharkút terrestrial vertebrate
locality has yielded several vertebrate taxa since its discovery. Scincomorphan
lizards are also represented in this fauna by several jaw fragments. The most
abundant of these is represented by seven dentary fragments and an
indeterminate jaw fragment with characteristic teeth. The hypertrophied
splenial, the heterodont dentition, the cementum deposition at the bases of the
teeth, and the large subcircular resorption pits assign this type to the family
Teiidae. The dentition is composed of conical, monocuspid teeth in the mesial
region and transversely widened bicuspid teeth in the distal region. This
morphology is well known in members of the subfamily Polyglyphanodontinae.
Based on their dental morphology the Iharkút finds can be easily assigned to
the genus Bicuspidon. This genus is known from two species, B. numerosus Nydam
et Cifelli 2002 from the Albian-Cenomanian of Utah (North America) and B.
hatzegiensis Folie et Codrea 2005 from the Maastrichtian of the Hat¸eg Basin
(Transylvania, eastern Europe). The Hungarian specimens differ from Bicuspidon
numerosus in that the latter has bicuspid teeth in the distal part of the tooth
row, in contrast to the Hungarian species, which has two monocuspid teeth in
the distal region, one equal to the size of the preceding teeth, and one less
than half the size of the former one. The presence of monocuspid teeth at the
end of the tooth row resembles B. hatzegiensis, but since the very end of the
tooth row of the latter is not known it is not possible to determine if B.
hatzegiensis also has two monocuspid teeth distally. Thus it is not impossible
that the Hungarian specimens represent a new species, but at present the lack
of necessary information allows its determination only as Bicuspidon aff.
families (summarized in the paper of Csiki-Sava et al. 2015 ), but in most cases, these fossils are isolated elements.
The ichthyofauna of the Late Cretaceous (Santonian) Iharkút vertebrate locality (Csehbánya Formation, western Hungary) was

Recently, Sancho et al. ( 2016 ) demonstrated a new approach in geostatistical analysis. This is the family of
