Pinus yorkshirensis is an extinct species of pine tree. The fossil pine cone came from Hauterivian and Barremian-aged sedimentary rocks located in the Speeton Clay Formation in Yorkshire (hence the species epithet).
The type specimen of Pinus yorkshirensis, BiRUG BU4737, was discovered during a field trip with the University of Birmingham to the Speeton Clay Formation. It is one of four known fossil pine cones from Europe and it was found within a weathered concretion that had split into seven fragments. It was 5 million years older than the previous record holder, Pinus belgica.
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.
Pinus yorkshirensis was named and described by Ryberg et al. (2012).
The preserved cones of P. yorkshirensis are conical in shape.
