Youngest Sea Scorpion Fossil Found in Australia paleontology science
Eurypterida
, an extinct order of aquatic predatory invertebrates that lived from the early Late Ordovician to the Late Permian epoch.A large, incomplete fragment of’s cuticle with distinctive ornamentation was found in the rural town of Theodore in central Queensland in the 1990s.It was examined by Dr. Andrew Rozefelds from Queensland Museum and Central Queensland University and Dr. Markus Poschmann of the Generaldirektion Kulturelles Erbe RLP.
“Using published dates for volcanic sediments preserved in the coal measures the Theodore sea scorpion has been accurately dated as living 252 million years ago and after extensive research this particular fossil turned out to be the last eurypterid known from anywhere in the world,” Dr. Rozefelds said.. The eurypterids disappeared, along with other groups of animals, at this time.”
“This new tantalizing fossil helps fill the gap in our knowledge of this group of animals in Australia, and indeed worldwide,” he added. “This particular sea scorpion would have been among the largest predators in the lakes and rivers of the Theodore area at this time.”
