Hey guys, gals, and fellow tetrapods!

Here is Dreadnoughtus schrani from episode 49 of the Skeleton Crew Podcast.

The genus name is derived from dread (English verb, to fear greatly) and nought (English noun, nothing). The specific name is in honor to American entrepreneur Adam Schran who help financed the work done on Dreadnoughtus.

The phylogeny of D. schrani is that it is a titanosaur. Within macronarians (sauropods with a large opening of the nares and full tooth row) there is a split between camarasaurids and Titanosauriformes. The later are macronarians more closely related to brachiosaurids and titanosaurs than to Camarasaurus. Within this clade there is Somphospondyli, which contains members more closer to Saltasaurus then Brachiosaurus. Further within somphospondylans, there is the clade Titanosauria where all the massive sauropods we call titanosaurs (i.e. Argentinosaurus, Alamosaurus, and Patagotitan) along with other closely related Cretaceous sauropods are contained. Current consensus on D. schrani placement in Titanosauria is that is a sister or a close sister relative to the clade Lithostrotia.

D. schrani was found in the Cerro Fortaleza Formation, radiodated to the Campanian to Maastrichtian of the Late Cretaceous, 76 to 70 mya. The environment was interrupted to be a fluvial sediment. This would have been a floodplain type environment, the fossils were D. schrani were found was interpreted to be a crevasse splay, which is when a river break a natural levy and creates a small delta. Based on wood fossils, it would have been a gymnosperm dominated environment (plant majority gymnosperm than angiosperm). Known contemporaries include exceptionally large titanosaur Puertasaurus, a megaraptorid Orkoraptor, Austrocheirus a peculiar ambiguous averostran, a iguanodontian, and turtles and crocodyliforms.

Information came from the video on Dreadnoughtus by the SkeletonCrew Podcast; The video with more detail, nuance, and fun banter can be found here: www.youtube.com/watch?v=GhULxh…

Here are various sketches of the titanosaur Dreadnoughtus. This was made as a part of a sketchbook assignment. The prompt word was 'power' and the sketches had to be drawn using red colour pencil. I'd chosen Dreadnoughtus as my subject because I thought "what could be more symbolic of power than something the 'fear nothing'".
