Mini T. Rex Could Be Missing Link

A private owner has donated a fossil that could change the way we think about Tyrannosaurus and their development.

Some scientists believed the T.Rex evolved to its enormous size, then its arms shrank, when they were no longer needed. The new discovery, though, shows that the tiny-armed killing machine may have evolved from a much smaller killing-machine-with-tiny-arms. This totally rearranges the previous T.Rex evolution paradigm.

The 125 million-year-old fossil dinosaur, unearthed in China and dubbed Raptorex kriegsteini, is “as close to the proverbial missing link on a lineage as we might ever get for tyrannosaurs,” Sereno said.
