New research from the Briggs Lab reporting on the oldest Eurypterids

New research from the Briggs Lab reporting on the oldest known eurypterid fossils from Iowa was recently published in BMC Evolutionary Biology. Eurypterids were large aquatic arthropods, that are ancestors to modern spiders and lobsters, for example. This new species, called Pentecopterus, lived about 467 Ma, during the Ordovician. Despite the age of this fossil, remarkable preservation was observed. Here is a link to some other media coverage. This research involved collaboration between Yale and the University of Iowa.

Earlier in August, the Briggs Lab published a paper in Biology Letters titled ‘All the better to see you with‘ reporting on the visual system of the eurypterids and the divergent ecological roles between a number of these species. This was a follow-up paper to ‘What big eyes you have‘, published last year. Looking forward to the next paper!
