The very similar greenish grey sandstones with red spots and the placoderm Byssacanthus pieces are decribed in the database fossiilid.info as from Narva stage (Middle- Late Eifelian, Middle Devonian) Talking about Eifelian tristichopterids I do not know any bigger forms, I just have heard about Tristichopterus. But judging by the size and the
Dear Guys, Yesterday I splited oil shale erratic that is originated from North Estonia and is Kukruse stage (Sandbian, Late Ordovician) in age and I found this intriguing segment... I found very similar shape in Chasmataspis drawings and fossil photo, please note that Chasmataspis second segment is also serrated in the lateral edges and it is also little segmented in the mid part. The age of Chasmataspis is Middle Ordovician, ir is found only in one place of USA and its age is up to 460 million years. So it is one question- Could it be the new member of Chasmataspididae family w
Dear Guys, I recently found one small (5 mm width) and interesting specimen that can belong to primitive xiphosuran by the appearance of cephalothorax. It has not any jaws as trilobite and the preserved eye is merostomate like (not any small eyes but only protuberant area, similar to eurypterid or other chelicerate eyes). The rick is found in Varena town, South Lithuania and the age should be about 475 million years. Please help to confirm the primitive chelicerate if you could. Regards Domas
