The fossils of Madison County (Montana)

ALDER, MONTANA – Standing at the foot of the mountains, I look to the east. It’s still early and I have hiked up here alone to gather my thoughts. I can see why they call this “Big Sky Country.” The tree-covered foothills of the mountains behind me give way to rolling scrubland. Stunted trees mark the edges of dry creek beds cut into the soft rocks below. This is southwest Montana, and I’m here to hunt.

Go behind the scenes with paleontologist Sam Heads as he hunts for fossils in Montana in this article from the U of I News Bureau.

Ancient ‘fig wasp’ lived tens of millions of years before figs

INHS Paleontologist Sam Heads found an ancient fig wasp that pre-dates any known fig trees. According to Heads, “This is a tiny parasitic wasp, it’s the smallest fossil wasp found in this particular deposit and it’s the oldest representative of its family. More importantly, it’s possible that this wasp was fig-associated, which is interesting because it’s Early Cretaceous, about 115 to 120 million years old. That’s a good 65 million years or so prior to the first occurrence of figs in the fossil record.”
