During July 2015, Tim Smithson and Sarah Finney headed to the mountains of West Virginia, USA, with project partner Stephanie Pierce from the Museum of Comparative Zoology, Harvard University, where Romer was once Director, and New York State University geologist Gordon Baird. They were following in the footsteps of a field party sent out by Romer in the 1950s to find early Carboniferous tetrapods.
During their travels they met a local fossil collector Bob Peck who kindly introduced them to his collecting sites in the Hinton area in the south of the state. Here the fossils are preserved in limestone and Bob reveals them by preparing the rocks in dilute acetic acid, just like Becky Bennion was doing last summer with material collected from the Scottish Borders.
As well as benefitting from Bob’s local knowledge, the 2015 team also had access to an excellent field notebook prepared by Romer’s original field party to guide them.
The geology of West Virginia is complicated, with the Devonian and Carboniferous rocks thrown into a series of folds during the formation of the Appalachian Mountains. The exposures are nearly all road cuts and fossils are scarce.
The 2015 party did have some success and returned to the Museum of Comparative Zoology with some nice fossil plants, a few bivalves and suite of disarticulated vertebrate remains. Time will tell if these include the elusive Romer’s Gap tetrapods. Some interesting fossil preparation lies ahead.
