The reason its study has taken so long is that Scotland lacked the means. It has been sitting in a museum for the past century waiting to be examined. The country simply could not afford to fund one fossil as it was not one of their priorities. It also lacked home based scholars who have specified in the niche to make the study less expensive.
With enough homegrown vertebrate scientists in the country now, the fossil has been moved to a research center to understand the animal thoroughly. The first handle was that the fossil was preserved with a rock that made studying it tough.
"Look, a lot of specimens are in museums for a long time before they're studied, so it's easy to go back to that trope," said Steve Brusatte of the University of Edinburgh. "I don't think there were any vertebrate paleontologists here at the time. One of the reasons I came here is that I figured it was really under-studied,"
The scientist did concur however that there was a good chance that they would find a new dinosaur species in the process. He said that the creature stayed too far north to have been discovered anywhere else.
