RE: 300 MY old Cockroach Fossil Found



Actually, there is a paleontologist (Heather Wilson) who has done a lot of work with arthropleurids in recent years.  Phylogenetic analyses place them nested within modern millipedes, although to be fair outside of the clade of familiar species.  See:

and

Here is the url for the GSA abstract.  Note that the giant roach is NOT
_Arthropleura_ (which is a millipede)

     I don't think Arthropleura is a millipede, no one knows what athropleurids actually were, but they had completely different appendage and respiratory structure to modern myriapods, HUGE too, up to 2m, left charecteristic 'caterpillar tracks' in Carboniferous sediments from Nova Scotia.

, but is presumably the new genus &
species of insect.
