Tammy knew one local Paleobiology professor, Dr. Colin Sumrall. When she told him about the discovery her daughter has made, he was really excited to see it in person. They scheduled the meeting and the very next day they were in his office. Ryleigh was so attached to her discovery that she was hugging the fossil and when the professor asked her to show it to him, she just didn’t give it to him that easily and simply showed him the fossil while holding it in her hands. The professor was smiling on this act of hers and just by the look, he knew it is something extraordinary. He told them that what she has found is an ancient creature. What is the name of the creature?
