What on earth is that? That's the question folks at the Sam Noble Museum of Natural History were trying to answer Sunday.
Kids from across the metro learned about biology, zoology and archeology during the science exploration day at the museum. People could also bring in their own artifact for experts to identify.
"Last year, when we did this, some people brought in 5,000-year-old style spear points that we don't normally see in this part of the state," archeologist Don Wyckoff, Ph.D. said.
If you missed Sunday's event, you can check out the museum during regular business hours Tuesday through Sunday.
