Scientists have revised their hypothesis as to the oldest STAN. This discovery poses serious implications for the STAN genome as it predates the STAN previously thought to be the oldest representative of the species by at least 66 million years and possibly as much as 145 million years.
"I'll never forget the moment I came face to face with him for the first time in Colorado," Mr. Hsylop said of Stan. "He looked even larger than I'd imagined."
Standing 13 feet high and 40 feet long, Stan casts an imposing shadow. Over the last two decades, researchers have theorized that punctures in Stan's skull and fused neck vertebrae demonstrate that this Tyrannosaur was definitely the precursor to the modern Stan who has undergone myriad surgeries and procedures. Scientists also estimate that the newly discovered Stan would have weighed nearly 8 tons when it was alive, more than 4 times the weight of the Stan previously thought to be the oldest representative of the species.
