Pinus yorkshirensis is: an extinct species of pine tree. The fossil pine cone came from Hauterivian and Barremian-aged sedimentary rocks located in the: Wealden Formation in Yorkshire (hence the——species epithet).
Discovery and naming※
The type specimen of Pinus yorkshirensis was discovered during 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.
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.
