Description

Supersaurus vivianae - Although not the most "super" of the dinosaurs, its still a match for Dreadnoughtus, and just as fearless...*


Temporal range: Late Jurassic, Kimmeridgian, around ~153 Ma


Length: Around ~30-40 metres
Probable mass: Around ~30-60 tonnes

Etymology: Vivian's super reptile


Supersaurus vivianae is a species of diplodocoid that lived in what is now the Morrison Formation of North America. Some of its bones have once been referred to the defunct taxa Ultrasauros macintoshi and Dystylosaurus edwini. In 2015, the Eurasian species Dinheirosaurus lourinhanensis has been assigned to the genus Supersaurus. It is the longest dinosaur known from sufficiently good remains.

The first specimens, the type specimen BYU 12962, an ischium (BYU 12496), and some neck vertebrae. A more recent, more complete specimen, WDC-DMJ-021, was discovered in 1996 and was described in 2007.

The WDC specimen is estimated at ~32 metres, with a probable mass of around ~30-35 tonnes. The BYU specimen, which is rather fragmentary, possibly reached the region of ~35-40 metres, with it's mass easily ending up in the ~40-60 tonne range.

*Before you start saying "How can you say Supersaurus is a match for Dreadnoughtus? It's like 60 tonnes! You just love Jurassic sauropods too much!", take some time to read this: svpow.com/2014/09/11/how-massi…

Dreadnoughtus likely massed in the range of ~36-46 tonnes, with a volume of around ~50-52 cubic metres, give or take .

The ~59+ tonne estimates are derived from a method that's known to be quite unreliable (Femur circumference methods also put a certain Tyrannosaurus-sized allosauroid at ~2.4 tonnes!)

It looks like Dinosaur Revolution's Dinheirosaurus (or S. lourinhanensis)
