Noah had to use duct tape to get this one on the ark

I suppose this one ate coconuts as well?

CHICAGO (Reuters) - Fossils from two newly discovered meat-eating dinosaurs that lived in the Sahara Desert 110 million years ago paint a fearsome picture of life in Africa's Cretaceous period, which appears to have been teeming with unusual carnivores.

University of Chicago paleontologist Paul Sereno unearthed Kryptops palaios, a short-snouted, hyena-like beast, and Eocarcharia dinops, a shark-toothed, bony-browed killer in a 2000 expedition.

Both were about 25 feet in length -- and on the prowl for meat.

"These are two of three that we dug up. To have three large predators in this area is really extraordinary," said Sereno, who describes the dinosaurs in the scientific journal Acta Palaeontologica Polonica.

Sereno said the animals lived in the southern landmass that was known as Gondwana, where distinctive meat-eaters arose, many of which bear no likeness to the better-known North American predator of the time, Tyrannosaurus rex.

Kryptops was a scavenger and had a uniform series of relatively pointy teeth and a short snout. "The idea was that the animal was sticking its head into carcasses," he said.

Eocarcharia, or "dawn shark," is known for its blade shaped teeth and bony brow.

"The teeth are very narrow side-to-side. They are blade-shaped for cutting. This animal specialized in capturing live prey and severing limbs. It was definitely a sabotage attacker, waiting for an opportunity to jump at something," Sereno said.

Eocarcharia and members of the group carcharodontosaurids gave rise to the biggest predators on southern continents, matching or exceeding Tyrannosaurus in size.

Sereno said the fossils epitomize the split world of dinosaurs during the Cretaceous period, which occurred because the continents began to drift apart.

"There is nothing quite like it in North America Cretaceous because after a few fits and starts, the tyrannosaur came into being and they are often alone as the large predatory dinosaur."

I am very grateful to be living in the Holocene Epoch, thank you very much.

It had a huge neck, see...

RIO DE JANEIRO (Reuters) - Brazilian and Argentine paleontologists have discovered the largely complete fossil of a new species of giant dinosaur that roamed what is now northern Patagonia about 80 million years ago.

The herbivorous Futalognkosaurus dukei measured an estimated 105 feet to 112 feet from head to tail and was as high as a four-storey building. It is one of the three biggest dinosaurs yet found in the world.

"It's a new species, it's a new group," Argentine paleontologist Juan Porfiri told a news conference in Rio de Janeiro on Monday.

The find pointed to a new lineage of titanosaurs, with particularly bulky necks, he said.

"Its neck was very big in diameter, strong and huge."

Evolution is not tidy

And our family tree has many dead branches:

WASHINGTON - Surprising research based on two African fossils suggests our family tree is more like a wayward bush with stubby branches, challenging what had been common thinking on how early humans evolved.

The discovery by Meave Leakey, a member of a famous family of paleontologists, shows that two species of early human ancestors lived at the same time in Kenya. That pokes holes in the chief theory of man's early evolution — that one of those species evolved from the other.

And it further discredits that iconic illustration of human evolution that begins with a knuckle-dragging ape and ends with a briefcase-carrying man.

The old theory is that the first and oldest species in our family tree, Homo habilis, evolved into Homo erectus, which then became human, Homo sapiens. But Leakey's find suggests those two earlier species lived side-by-side about 1.5 million years ago in parts of Kenya for at least half a million years. She and her research colleagues report the discovery in a paper published in Thursday's journal Nature.

The paper is based on fossilized bones found in 2000. The complete skull of Homo erectus was found within walking distance of an upper jaw of Homo habilis, and both dated from the same general time period. That makes it unlikely that Homo erectus evolved from Homo habilis, researchers said.

Overall what it paints for human evolution is a "chaotic kind of looking evolutionary tree rather than this heroic march that you see with the cartoons of an early ancestor evolving into some intermediate and eventually unto us," Spoor said in a phone interview from a field office of the Koobi Fora Research Project in northern Kenya.
