WASHINGTON (Reuters) - In Europe 150 million years ago, this dude was the biggest, baddest bully in town.

Two scientists in Portugal announced on Wednesday that they have identified the largest carnivorous dinosaur ever found in Europe, a 33-foot-long (10-meter-long) brute called Torvosaurus gurneyi that was the scourge of its domain in the Jurassic Period.

"It was indeed better not to cross the way of this large, carnivorous dinosaur," said paleontologist Christophe Hendrickx of Universidade Nova de Lisboa and Museu da Lourinhã in Portugal.

Torvosaurus gurneyi was an imposing beast. It was bipedal, weighed four to five tons, had a skull almost 4 feet long, boasted powerful jaws lined with blade-shaped teeth four inches long, and may have been covered with an early type of feather, Hendrickx said.

"Torvosaurus gurneyi was obviously a super predator feeding on large prey like herbivorous dinosaurs," Hendrickx said.

Remains of the new species were unearthed in Portugal by an amateur fossil hunter in 2003 in the rock cliffs of Lourinhã, a small town about 45 miles north of Lisbon, Hendrickx said. He said fossilized embryos probably belonging to this species were identified last year in Portugal.

The findings were published in the journal PLOS ONE.

At the time that Torvosaurus prowled the landscape, the region was a lush river delta with abundant fresh water and vegetation. The area teemed with dinosaurs and flying reptiles known as pterosaurs, primitive birds, crocodiles, turtles and mouse-sized mammals, according to paleontologist Octávio Mateus, also of Universidade Nova de Lisboa and Museu da Lourinhã.

Plant-eating dinosaurs living in the area included the huge, long-necked Lusotitan, the armored, tank-like Dracopelta and the spiky-tailed Miragaia, Mateus added.

The two scientists said this is the second species of the genus Torvosaurus. The other one, Torvosaurus tanneri, lived at the same time in North America. It was known from the states of Colorado, Utah and Wyoming and was identified in 1979.

Its genus name, Torvosaurus, means "savage lizard." Its species name, gurneyi, honors James Gurney, the author and illustrator of the popular "Dinotopia" book series.

Torvosaurus gurneyi was not the only meat-eating dinosaur in its neighborhood. For example, there was a European species of the well-known North American Jurassic predator Allosaurus, but the Torvosaurus found in Portugal was larger.

Torvosaurus gurneyi not only is the largest known meat-eating dinosaur from Europe, but is the biggest land predator of any kind ever found on the continent, they added.

There were larger dinosaur carnivores elsewhere, however.

Tyrannosaurus in North America, Carcharodontosaurus and Spinosaurus in North Africa and Giganotosaurus in Argentina all were bigger, but appeared on Earth much later than Torvosaurus, during the Cretaceous Period that followed the Jurassic Period.

"This animal, Torvosaurus, was already a fossil for 80 million years before the T. rex ever walked the Earth," Mateus said.

During the Jurassic Period from about 200 million years ago to 145 million years ago, carnivorous dinosaurs generally were medium-sized, with an average length of about 7 to 16 feet. Larger ones like Torvosaurus, Allosaurus and Saurophaganax arrived in the late Jurassic Period.

The Dinosaur mega beast reined for 135(+/-) Ma. This represented dominance through brawn of strength and size. Cretaceous species included the Tyrannosaurus Rex, extending reptilian brute force dominance across the Jurassic Cretaceous transition. This begs any assertion of meteorite extinction, particularly since at-least late Cretaceous beast fossil remains indicate a warm blood relatively intellectual species. I would argue evidence of an paradigm shift is a increasing conundrums of highly selective extinction by the Chicxulub asteroid impact, or multiple End Cretaceous impacts. Which must also infer a differential gradual specie extinction for the final stage of the Cretaceous Period.

We need only discern a 417Ma covariance of pairs with the Phanerozoic Era. Such a repeating and precise pattern indicates a Galactic Arm Physical Geologic Driver. Further modeling of which infers a 139.5Ma SOL Galactic orbital period, with Arm expansion rates that also precisely pair Near Side Central Bar and Far Side Central Bar spirals for Major, Nominal and Minor equilateral equivalence. This adds to mounting evidential conundrum of Star Galactic orbitals that defy Kepler Planetary Laws that Dark Matter Hypotheses fails, that Birkeland Electric Filamentary Universe addresses, and that the above Physical Geologic Driver all have differentials, they do not completely work in unison. Perhaps a common denominator involves our Doppler perception of the Hubble Red shift. The shear extent across the sciences compounds our paradigm threshold against change.
