Auspex Posted April 16, 2015 Share Posted April 16, 2015 Do I understand that these strange worms are abyssal, and that the case being made is that plesiosaurs were deep-water pelagic dwellers? The logic eludes me; haven't most abyssal deposits been subducted and recycled? The lack of abyssal fossils seems not so much a mystery to me.

MgTattooer86 Posted April 17, 2015 Share Posted April 17, 2015 Reminds me of a story I read about porcupines eating bones and teeth from primates in Asia. If you show them a transitional, they'll ask for two more. Link to comment Share on other sites More sharing options...
DPS Ammonite Posted April 18, 2015 Share Posted April 18, 2015 (edited) Do I understand that these strange worms are abyssal, and that the case being made is that plesiosaurs were deep-water pelagic dwellers? The logic eludes me; haven't most abyssal deposits been subducted and recycled? The lack of abyssal fossils seems not so much a mystery to me. Here in the San Francisco Bay area there are lots of abyssal sedimentary deposits preserved in the Jurassic and Cretaceous Franciscan Assemblage in the form of mostly greywacke turbidites and cherts that were scraped off the descending oceanic plate onto the continental plate in the accretionary wedge. Macro fossils, save for a handful of clams and ammonites, are absent including plesiosaurs, pliosaurs and mosasaurs. I don't know why plesiosaurs, pliosaurs and mosasaurs are not found here. Here are reasons why they may not exist as fossils: they were never common; they were not buried in a timely manner to preserve them; they were eaten by the worms; they were destroyed by the turbidite flows, they did not survive diagenesis and metamorphism. Maybe Boesse can give us his answer. Edited April 18, 2015 by DPS Ammonite My goal is to leave no stone or fossil unturned.
