#FossilAdventCalendar Day 18
The original of this cast #skeleton, displayed in the #ArizonaMuseumOfNaturalHistory, was found along the Northern Dvina River. It's from Inostrancevia alexandri, a #gorgonopsian from the #Permian. Its huge size is the first thing you'll notice about it; this #animal and its relatives were clearly among the most imposing #predators of their time. Look closer and you'll see that it shares many traits with #mammals, of which it was a not-very-distant relative.

This #whale-sized #marine #reptile in the #RoyalTyrrellMuseum is the #ichthyosaur Shastasaurus sikkaniensis. Unusually, it was not only one of the earliest members of its group, but one of the very largest. Its #species name comes from where it was found, along the Sikanni Chief River which flows out of the #RockyMountains of #BritishColumbia 🇨🇦. Its #genus name comes from Mt. #Shasta in the #CascadeRange, where other species of this Triassic titan have been found.

Today we return to the #Nordic countries, specifically to the #Nationalmuseet in #Copenhagen 🇩🇰 to meet the #aurochs (Bos primigenius), the #extinct wild ancestor of modern #cattle. This #bull lived and died over 10,000 years ago in #Vig, on the #Danish island of #Sjaelland, but unlike many #IceAge #megafauna, it survived until surprisingly recently. In #Denmark, it persisted in #Jutland until around 2000 years ago; the last aurochs died in #Poland only in 1627.
