Fossil Scorpions
Eurypterids.net
Proscorpius osborni was the first scorpion found as a fossil in the Late Silurian rocks of New York State. For more information, see Clarke & Ruedemann (1911-1912) "The Eurypterida of New York." The scorpion pictured above is one of many I found over the years in eastern New York (Phelps Waterlime Member of the Fiddlers Green Formation, Bertie Group). This and other scorpion specimens are described in a publication,  "A restudy of the Fossil Scorpi- onida of the World" by Erik N. Kjellesvig-Waering (1986), Palaeontographica Americana 55: 1-287

Pandinus imperator Koch
LEFT: is a mounted specimen of a large African scorpion that I pur- chased years ago at the Field Museum of Natural History in Chicago. This specimen is 19 cm (nearly 8 inches) in length and is one of the largest scorpions living today. Pandinus lives in hot, humid tropical forests in the coastal coun- tries of West Africa. So not all scor- pions live in deserts...
   The "Scorpion Eurypterid" may have had a poison gland, though we do not have all of the evidence we need to prove this. Take a look at
Paracarcinosoma scorpionis and the highly curved telson of this eurypterid. There can be no doubt that this was used against prey, but was it poisonous?
Emperor Scorpion
Note the stinger (telson) on this specimen. And note that the 400+ million-year-old (fossil) scorpion above also is much like living scorpions in basic structure - even though Silurian scorpions are believed to have been aquatic. The stinger has been around for a very long time. Did any of the eurypterids have a 'stinger' during their history on the planet? Take a look at Eurypterid Gallery 11.
