It's a team effort," De Cook said of the discovery.
De Cook said she and her colleagues would uncover the bones Friday and then a group from the Fox and Sac Lapidary Club as well as William Penn University would be out Saturday to take the bones out of the ground.
Dave Brenzel of the Indian Creek Nature Center said he was pleased that the bones discovered on the east side of the dig site Friday were in good condition.
Toward the end of this past year's digging season, volunteers were uncovering bones in deteriorated condition on the east side as it was drier than the west side of the dig site. If the area is dry, oxygen can get to the fossils and degrade them. Volunteers had to wrap fossils found on the east side in plaster to preserve them. However, the bones found Friday were deeper and were in good condition.
“These bones are waterlogged,” which is a good thing, he said.
"We're just starting the season," Bresco said. "We're picking up where we left off."
