New species of tiny tyrannosaur foreshadows rise of T. rex

A newly discovered, diminutive—by T. rex standards—relative of the tyrant
king of dinosaurs reveals crucial new information about when and how T. rex
came to rule the North American roost.

Meet Moros intrepidus, a small tyrannosaur who lived about 96 million years ago
in the lush, deltaic environment of what is now Utah during the Cretaceous period.
The tyrannosaur, whose name means "harbinger of doom," is the oldest Cretaceous
tyrannosaur species yet discovered in North America, narrowing a 70-million-year
gap in the fossil record of tyrant dinosaurs on the continent.

"With a lethal combination of bone-crunching bite forces, stereoscopic vision,
rapid growth rates, and colossal size, tyrant dinosaurs reigned uncontested for
15 million years leading up to the end-Cretaceous extinction—but it wasn't always
that way," says Lindsay Zanno, paleontologist at North Carolina State University,
head of paleontology at the North Carolina Museum of Sciences and lead author of
a paper describing the research. "Early in their evolution, tyrannosaurs hunted in the
shadows of archaic lineages such as allosaurs that were already established at the
top of the food chain."

Medium-sized, primitive tyrannosaurs have been found in North America dating from
the Jurassic (around 150 million years ago). By the Cretaceous—around 81 million
years ago—North American tyrannosaurs had become the enormous, iconic apex
predators we know and love. The fossil record between these time periods has been
a blank slate, preventing scientists from piecing together the story behind the ascent
of tyrannosaurs in North America. "When and how quickly tyrannosaurs went from
wallflower to prom king has been vexing paleontologists for a long time," says Zanno.
"The only way to attack this problem was to get out there and find more data on these rare animals."

1. New species of tiny tyrannosaur foreshadows rise of T. rex

Did you bother to read the article???

Let me ask you a question.

How can a creature who supposedly lived 96 million years ago be a foreshadowing of a creature who supposedly lived (well the medium sized) 150 million years ago?

So the T-Rex line shrink then grew? How did they figure out it was 97 my old? It was found relatively shallow?

If that was a fossil they could not tell its age from inner bone scoping- it would be all mineral ! Unless actual marrow and calcium from teh orignal animal was still extant, so that it wasn't fully fossilized!

How did they rule out this was not simply a bay T-Rex?

They have left more unanswered questions than answers provided! It is always awesome when we find dino remains, but this article has serious gaps in ti!

4 bone sections of a leg and they come up with all that info on this creature? Plus a nice polaroid to boot from a partial leg! Be honest at least with yourself- If a creationist made this discovery and wrote a huge articel on it from the paucity of physical material discoverd- you would probably howl like crazy for the amount of material they filled the gaps with!

2. Lmao.

1. No. T.Rex lived millions of years after this one.

2. No. T.Rex lived millions of years after this one.

3. Yes, they can tell. Learn about it. For once.

4 They are way, way, way smarter than you and can tell the difference, unlike you and the loons you worship.

Yes, if a creationist wrote this article I'd look up the original source and see for myself. Because creationists have been shown to be liars and charlatans over and over again.
I've proven it here to you several times and is the reason you have me on ignore.

Read a book. A real book. Not a collection of fables from primitive goat herders.
Then maybe, just maybe, you'll have a clue.

Poor nolidad
