    Pompeii’s victims weren’t vaporized. They were indeed killed by a hot pyroclastic flow. The position of many of the bodies indicates it was hot enough to start cooking the bodies, causing the arms to pull into a pugilistic pose and the lips to pull back, but not hot enough to burn the flesh off completely, like in Herculaneum. There were additional falls of lapilli and ash that buried them the rest of the way. The substrate then hardened around them before they decomposed, leaving hollows with skeletons inside. Very few victims were actually preserved that way because the flow cooled a bit on the way through the city, so some bodies were burned away.

    I want to make sure it’s crystal clear for any creationists here, The paper is only saying that soft tissue was fossilized. Which is different from normal fossils, most of the time there is no soft tissue that also is fossilized. Most of the time it’s only the exoskeleton. This time they were able to 3-D image the fossil and found that the soft tissue was also preserved, giving us insight into the anatomy. For more info, check out the abstract of the paper in the description

      Your mistake here is thinking Creationists care about the truth or reality. If they did, they wouldn't be creationists. Good work providing context though.

    Trilobite limbs and antennae don't fossilize very often not because of them being "thin", there are plenty of examples of exceptionally preserved trilobites with long and thin spines perfectly preserved but which don't have even the slightest trace of the legs and antennae.
    This is because only the top part of trilobites had that unique callcite + calcium phosphate makeup that made them fossilize so well, while the underside didn't.

    As for paleontology, discovery of soft tissue is always welcome, bringing something surprising to light. No better than stomach contents that can tell part of life style to reconstruct. Curiosity is how that might happen. This is a taphonomic issue rather than a paleontological one though. Thanks for your posting.

    Is it known whether the brachiopods attached while the animal was alive, or post mortem?

    • @RaptorChatter
      @RaptorChatter  5 месяцев назад +2

      When alive! Trilobites shed by detaching the side lobes of the head, so since these are basically complete, with no broken up skeletons it's likely that they were attached in life, as opposed to this one dying and then only brachiopods finding refuge on it, as opposed to other scavengers feeding and disarticulating the body.

      It's possible, but not that likely due to the nature of chelicerae, and how unique they are compared to other feeding structures.

      @alexanderbaca7352 5 месяцев назад

      @@RaptorChatter I appreciate your response 🙌 I think it's interesting because some early Cambrian trilobites have telson like tails. Also, isn't it true that sanctacaris, which is often considered the most basal of the chelicerates, does not have chelicera itself? I myself believe that there is an argument to be made that all chelicerates are descended from trilobites, and that horseshoe crabs represent an early descendant off from the other extinct trilobite group.

      No, it's not that great of preservation. Plus it's important to remember that even in working bodies DNA is made to fall apart, it's how cells divide. So once an animal dies one of the first things to start happening even if fossilized is the DNA breaking apart.
