Newly discovered T. rex lookalike with an unusual skull terrorized Patagonia 80 million years ago

Patagonia, the fine article is from CNN, kinda South of the Border.

(CNN)Paleontologists in Argentina have identified a previously unknown species of dinosaur that would have used its huge claws, powerful bite and keen sense of hearing to hunt prey in Patagonia 80 million years ago.
The fossilized remains of Llukalkan aliocranianus include a superbly preserved and uncrushed braincase and were unearthed in the Bajo de la Carpa Formation in Argentina. Llukalkan means "the one who causes fear" in the language of the indigenous Mapuche, and aliocranianus is Latin for "unusual skull."

The “One Who Causes Fear” – Extremely Powerful New Meat-Eating Predator Discovered

The “One Who Causes Fear” – Extremely Powerful New Meat-Eating Predator Discovered:

[...] Around 80 million years ago as tyrannosaurs ruled the Northern Hemisphere, this lookalike was one of 10 currently known species of abelisaurids flourishing in the southern continents.

A fearsome killer, Llukalkan was “likely among the top predators” throughout Patagonia, now in Argentina, during the Late Cretaceous due to its formidable size (up to five meters long), extremely powerful bite, very sharp teeth, huge claws in their feet and their keen sense of smell.

    But couldn't quite survive the big-ass meteorite.

    Guess who did: the little mice whose descendents are wielding the shovels to excavate the creature. Ah! Not causing much fear now are we?

        Most of them don't. We only see the residue, and only part of that. If you want to argue that the dinosaurs had a highly technical civilization, there is little evidence to show you are wrong.

            It is unlikely.

            On the other hand, what does unlikely mean?

            It's unlikely you'll die today, but 100,000 people already have (estimated.)

            It's like that with fossils. Lots and lots of bodies have lived and died and been completely recycled leaving no trace.

            But there were so many bodies that even though only a tiny percentage are preserved (as it's very unlikely for them to be preserved) that still leaves lots and lots of specimens to be found.

            And we've been getting better and better at finding specimens. So more and more examples are found.

            It still amounts to an exceptionally thin, and not particularly random, sample for most species.

            You are thinking of the Permian Triassic extinction event.
            It basically amounted to hitting reset on most of life on earth.

        These fossils almost didn't. They almost got washed into the ocean instead. It's only by the efforts of paleontologists and other fossil collectors that they avoided that fate.

            It just requires fossils to be buried for 80 million years and then become exposed now. There's a lot of burying processes like volcanic activity, floods, swamps, continental shelves, sand dunes, etc that can bury stuff - sometimes millions of years later. Then you need some sort of uplift and erosion for the stuff to come back to the surface at a later time. The Earth is a pretty active place and we presently have stuff going back 3 billion years.

      If that's really what got them. Quite a bit of supposition and 'probably' involved, but it's a decent best guess.

      It's interesting, however, that no subsequent terrestrial animals have developed the sheer size of the larger dinosaurs.

    >> Llukalkan means "the one who causes fear" in the language of the indigenous Mapuche,

    If they really wanted to scare us, they could have named it Majorsaurus aliocranius. Major means "the dog who has 'nipping' incidents" in the weaselly language of the indigenous Democrats, who went extinct because of overspending.

        We heat, but a dog that big that bites without warning is a serious problem.

        It’s like that old joke: when a chihuahua humps your leg, what do you do? Kick it. When a pit bull humps your leg, what do you do? Pretend you enjoy it.
