St. Petersburg's area is a is famous for its trilobites. I traveled in this city in last year. Today I show some photos of St. Petersburg city, paleo site and my finds. This is the most famous view of St. Petersburg - drawbridges. All tourists are watching on this bridge in white nights. White nigths are begining in June and it does not get dark at night because Petersburg is a northern city Sightseeing - the sphinx of Egypt stands on the embankment of the river Neva. This sphinx was bought in 19 century by the Russian Tsar I'm looking for fossils My findings. А lot of trilobites. I found whole trilobites too I prep trilobite Asaphus lepidurus
I found this in a newly created quarry about the middle of the Elgin member, Maquoketa formation, upper Ordovician of Fayette County Iowa last week. I'm thinking (judging from the little indentations on what I think is a cephalon) that this is some sort of Bumastoides?? I have never found one and it seems a fair bit larger (45mm x 35mm) than what the research that I have of this area indicates. Any thoughts would be greatly appreciated! Thanks.
