A small team of archaeologists, assisted by a large group of volunteers has unearthed what may be evidence of an ancient colony of pterosaurs living in what is now a central region in Oregon. In their paper published in the journal Lethaia, the researchers describe a two-week dig held in the summer of 2021 at the green breccia bed in the Hudspeth Formation, located northeast of Mitchell in Oregon.
