Key points:

- The palaeontologists have named it Koleken inakayali, a tribute to Inakayal, a deceased chief from the Tehuelche Indigenous people of eastern Patagonia, and a name from their Teushen language meaning "coming from clay and water."

- Various parts of the theropod's spine, hips, and limbs have been found, as well as bits of the skull.

- There are differences between Carnotaurus and Koleken. For example, the nasal bones of Koleken and Carnotaurus, for example, are easily distinguished from each other, and the lack of broad eyebrow horns in Koleken is another point that differentiates the two.

- "Whether Koleken and Carnotaurus lived side-by-side is unknown. The La Colonia Formation spans about five million years, and so the two carnivores could have been contemporaries or separated by millions of years." This also means that the titanosaur Titanomachya could have also been a contemporary dinosaur.

They have bits of the skull as well. From the paper:

The skull is represented by six bones: partially preserved right maxilla, fragmentary left maxilla, fragmentary left and right nasals, partial right postorbital, partial right frontal, partially preserved left and right squamosals, and fragmentary fused parietals

Here's a skeletal from Gabriel Lio (green is the material):

I saw the above video in my feed, but didn't realize it was of a newly described one. Thanks for sharing @Prehistory Resurrection
