Now, new research is focused on better understanding the T. rex’s little arms, according to foxnews.com.
Scientists took an arm off a T-rex called SUE from the Field Museum in Chicago for an intense scan at Argonne National Laboratory, part of the US Department of Energy.
The scan packed a punch about a million times as strong as a typical X-ray, and scientists hope that what they learn about the bones’ anatomy could tell them more about how it was used.
"These X-rays will give us a map of the blood vessels and muscle attachments in the bone, which have never been seen before," Carmen Soriano, a paleontologist with the Advanced Photon Source at the Argonne National Lab, said.
"This data could provide new insight into dinosaur biology, as well as clues to how SUE lived her life."
After the scans, they gave the T. rex arm back to the Field Museum. As for SUE, the specimen is considered to be the biggest T. rex discovered — it’s over 40 feet long and at the hip stands 3.9 tall, according to the Field Museum.
