Wiehenvenator is a genus of theropod dinosaurs from the group of Megalosauridae from the Middle Jura of Germany . The only known species is Wiehenvenator albati .
Discovery and naming
The fossil remains of the only previously known specimen were found in 1998 in the disused Pott sand-lime quarry north of the Lutternschen Egge summit , 256 m above sea level. NHN high mountain in the Wiehengebirge , found in the Haddenhausen district of the East Westphalian city of Minden . The geologist Friedrich Albat discovered this during a routine inspection on behalf of the LWL Museum für Naturkunde . The finds come from the Ornatenton formation in the North German Dogger group and are dated to the middle Callovian .
The dinosaur became known to the public in November 1999 through an article in National Geographic Germany magazine as the Monster of Minden . The find generated wide press coverage. As a result, the theropod first came to be known by the name used by the magazine.
In 2015, Oliver Rauhut , Tom Hübner and Klaus-Peter Lanser published that the find was a previously unknown species of megalosaurid. In the following year they provided the first description of the genus Wiehenvenator and the species Wiehenvenator albati . The authors honor the discoverer of the fossils with the species name .
description
The fossils include an upper jaw , an intermaxillary bone , two caudal vertebrae , a tooth, rib fragments and a complete rib.
According to the National Geographic article, a complete rib is one and a half times the size of an Allosaurus , and the tooth with the root is said to be about 30 centimeters long. This led to the initial assumption that the animal was about 15 meters long, making it the largest theropod found in Europe to date.
According to Mickey Mortimer, the complete skull was about one meter long, but the total length of the individual is seven to eight meters. According to Rauhut et al. the known specimen was most likely a large, not fully grown animal with a length of eight to nine meters, based on comparisons with the closely related Torvosaurus . This makes it the largest theropod discovered in Central Europe to date .
Others
The prepared finds are now accessible to the public in the LWL Museum für Naturkunde in Münster . As part of the permanent exhibition "Dinosaurs - The prehistoric times are alive!", A reconstruction of the find situation and a life-size static model are presented in addition to the original remains.
