Discovery and naming

The type specimen of P. yorkshirensis was discovered during a field trip at the University of Birmingham. It is one of four known fossil pine cones from Europe. It was 5 million years older than the previous record holder, Pinus belgica.[1]

The fossil was destroyed for science so scientists could study the fossil in more detail. All that remains are a few microscope slides and a single image. They are currently housed at Lapworth Museum of Geology.
