Named By: Oliver W. M. Rauhut, Tom R. Hübner & Klaus-Peter Lanser - 2016.
Classification: Chordata, Reptilia, Dinosauria, Saurishcia, Theropoda, Megalosauridae, Megalosaurinae.
Species: W. albati (type).
Size: Roughly estimated to be between 8 and 9 meters in length.
Known locations: Germany, Westphalia - Ornatenton Formation.
Time period: Callovian of the Jurassic.
Fossil representation: Partial skull and post cranial skeletal remains of a sub adult.
of Wiehenvenator were first discovered in 1998
around the Wiehen
Hills in Germany. When compared to some other theropod dinosaurs such
these fossils were noted as being of a potentially
huge size which led to estimates of up to fifteen metres in length
being recorded in popular media for many years afterward. However as
is often the case when people are more concerned with selling a
headline, most of these reports were gross overestimates.
These fossils got a fresh description in 2016 which saw them identified as a new genus called Wiehenvenator. This description came to establish Wiehenvenator as a megalosaurid theropod dinosaur (relative of Megalosaurus), with comparisons to genera such as Torvosaurus resulting in estimates of around eight to nine meters in length. The holotype individual of Wiehenvenator is also noted as being a subadult that was at least ten years old when it died, which means that fully grown adults may have been a little bit larger.
