Nógrádszakál is located in the northern part of Hungary beside the Ipoly River. To the north of the village, two gorges extend: valley of the Paris Stream and the Bertece Stream. In the dark grey tuffic marl deposited here, several leaf prints can be found. The first scientific collecting occurred between 1956 and 1962. Mostly species that indicate wetland or waterside areas existed here.
We collected the leaf print of a cornel species and a few petrified twig fragments.
Bánhorváti – Csiga-tető (hill-top)
Area of the Uppony Mountains is rich in scenic geological formations, which can be connected to the Miocene Epoch. We can find here plant remains of the Sarmatian Stage in many places. The Bánhorváti sand- and gravel quarry is located here, the layers of which are formed in the Lower Miocene. We collected oyster shells in huge numbers. On these shells, several traces of bioerosion can be discovered.
Near the village of Kazár, in the cut of a road leading to the Aranyosi-puszta (lowland), the most typical surface occurrence of the so called “Kazári Homokkő” (Kazar Sandtone) This sandstone is yellowish grey, lamellate, and also known as Pecten Sandstone, because between the layers vast number of shells and shell prints occur. Shark teeth are also can be found in this segment. Regarding the shells, low species diversity is typical.
