What did Steve Gatesy discover while on an expedition with Shubin on Ellesmere Island in Canada as noted in the nonfiction book, Your Inner Fish?

Steve Gatesy, a colleague of Shubin’s, was on an expedition with Shubin on Ellesmere Island in Canada. He moved a rock and suddenly the snout of a flathead fish was staring right back at him. It was an important find and Steve spent the entire rest of the summer digging in the spot to try to locate the flathead’s body. He worked meticulously, finding the rest of the fish tiny piece by tiny piece. Steve’s work paid off. The recovery of the water-land transition fossil was one of the most important ever discovered.
