Dinosaur Jr.: Here we have the Raptorex kriegsteini, as reconstructed by similarly sized humans.

The going theory about the Tyrannosaurus rex, in case you didn’t know, had been until very recently that this famous mega-dinosaur sported stumpy little arms as an evolutionary adaptation related to its jumbo body size. Then a fossil of Raptorex kriegsteini—perhaps 1/100th the size of T. rex, its descendant—came along and upended that notion with its own disproportionately puny forelimbs.  —KA

BBC:

A 3m-long dinosaur fossil from China which predates T. Rex by 60 million years is a blueprint for the mighty carnivore, say researchers.

They tell Science magazine that the fossil displays the same features as T. rex but in miniature.

The new species, Raptorex kriegsteini, would have weighed around 65kg; its descendants were 90 times as massive.

Scientists believe it could be the “missing link” between earlier species of dinosaur and T. rex.

The 125-million-year-old specimen suggests that T. rex’s characteristic big head with enhanced jaw, relatively small forearms and huge back legs were inherited from this much smaller dinosaur, and that the body type changed little over millions of years except in size.

No, too large unless you mean the smaller Raptorex then maybe. But how would you control them?

There are some scientists now seeing if they could re-create a dinosaur by re-activating the ancient reptile and dino genes in birds. Say use a Casowary or one of the other bipedal ground birds as a template. It could be done with just a control over which genes to turn on and off and at what time. From a lizard tail to less feathers and more scales to changing the articulation of the wings to more resemble clawed hands! Wish I could do that.

Probably would have made one heck of a good watch “dog.”
