Evidence of theropod dinosaurs from a Lower Cretaceous karst filling
in the northern Sauerland (Rhenish Massif, Germany).
Paläontologische Zeitschrift (advance online publication)
Theropod dinosaur teeth from a Lower Cretaceous karst filling in
Devonian reef limestone (Massenkalk) located near the village of Balve
on the northern margin of the Rhenish Massif, Germany, are described.
Palynological evidence indicates that the karst filling took place
during the Late Barremian to (Early) Aptian time interval.
Palaeontological excavations carried out during several years at the
Balve locality yielded remains of various animal groups, including
sharks, amphibians, turtles, crocodiles, pterosaurs, herbivore
dinosaurs, and, rarely, mammals. Of particular interest is an
assemblage of different theropod dinosaur teeth, which has been
characterized with the help of dental comparative morphometry. Based
on these analyses, the teeth material from the Balve excavation can be
assigned to five morphological groupings including dromaeosaurid and
tyrannosauroid theropods. Morphological comparison of the theropod
dinosaur teeth record with finds from other fossil localities in
western and northwestern Europe of similar age shows clear
similarities, but also some distinct differences.
