The dinosaur of the day: Siats

  • Megaraptoran theropod that lived within the Late Cretaceous in what’s now Utah, U.S.
  • Title comes from Siats, a predatory, man-eating monster in Ute Native American mythology
  • Just one species: Siats meekerorum
  • Species identify is in honor of John Caldwell Meeker, a geologist who bequeathed a fund for paleontological analysis on the Discipline Museum in Chicago, in addition to his spouse Withrow Meeker, and his daughter, Lis Meeker
  • Described and named by Lindsay Zanno and Peter Makovicky in 2013
  • Lindsay Zanno discovered Siats in a 2008 expedition of the Discipline Museum, led by Peter Makovicky. They collected it between 2008 and 2010
  • Probably the primary neovenatorid present in North America and the youngest (geologically) allosauroid
  • Holotype consists of a partial postcranial skeleton (vertebrae, a chevron, partial proper ilium, ischium and fibular, partial left tibia, some pedal phalanges).
  • Holotype is now on the Discipline Museum of Pure Historical past in Chicago
  • Holotype is of a juvenile (neural arches of vertebrae weren’t fused, so it wasn’t totally grown)
  • No cranial supplies discovered, aside from some enamel, so how its cranium regarded relies on kin
  • Probably had a pointy-ish head
  • Had lengthy, three-clawed arms
  • Might have had giant claws (not discovered, however based mostly on shut kin corresponding to Australovenator, Fukuiraptor, Aerosteon, and Megaraptor)
  • One of many largest identified theropods in North America
  • Zanno and Mackovicky estimated its to be as much as 39 ft (12 m) lengthy and weighing about 4 tons
  • Might have been comparable in measurement to Saurophaganax and Acrocanthosaurus
  • If measurement estimates are appropriate, Siats would have been one of many largest predators present in North America
  • Might have been an apex predator
  • If Siats is a neovenatorid, Siats exhibits that allosauroids nonetheless dominated North America (not tyrannosauroids) till the Late Cretaceous. However till final 12 months, there was plenty of debate of how you can classify megaraptors (they have been both neovenatorids or tyrannosaroids). Research of different megaraptorans have proven they’re carnosaurs that had tyrannosaroid-like options, through convergent evolution
  • Early tyrannosaurs, that lived on the time of Siats, would have been small
  • When Siats lived, most herbivores have been hadrosaroids and nodosaurs, however shortly after Siats, ceratopsians and ankylosaurs began thriving, and they’d have been too exhausting for Siats to deal with. This can be what allowed tyrannosaurs to develop and thrive (they have been extra suited to tackling these harder prey animals)

Enjoyable Reality:

Plant fossils are far more widespread than fossilized bones, however the two are very hardly ever discovered collectively.

  • Not as a result of they didn’t get buried collectively
  • Bones are preserved greatest in alkaline (primary) soil
  • Vegetation are preserved greatest in acidic soil
