"This spectacular 3D image of a newly discovered arthropod could rewrite the family tree of lobsters and spiders"
By Aviva Rutkin. New Scientist. « 3D fossil portrait could be the mother of all spiders »
« This 2-centimetre-long fossil arthropod, named Enalikter aphson, was found in rocks in Herefordshire, UK. It is the most recent addition to the megacheira, an extinct group of marine arthropods – and finding it in the 425-million-year-old rocks could indicate that megacheirans were distant ancestors of all arthropods alive today, including lobsters and spiders. »
