Fossil Sea Spiders

From National Geographic:


The well-preserved marine animals, called pycnogonids, were unearthed in 160-million-year-old fossil beds at La Voulte.
In a paper published online in the Proceedings of the Royal Society B, a team of French scientists describes 70 specimens–including the one seen above–from three distinct species found in the region’s Lagerstätte, a type of sedimentary rock formation.

Several other pictures can be found here and the article can be found here (not open access).

  1. Wow. Such things b-movies are made of.
    It’s so well preserved, I wonder if it’s exoskeleton was particularly thick?

  2. Glendon: It looks fairly similar to a modern sea-spider, and I don’t believe their particularly hard-bodied animals.
    Seeing as the previous tally of fossil pycnogonids of any description was probably less than ten individuals, this is a fantastic find.

  3. So, does this help clarify the taxononmy of sea-spiders?
    I’d really like them to turn out to be Anomalocaris long lost cousin.
