Radiodonts: 'Giants' of the Cambrian
The Radiodonts were a highly diverse lineage of Stem-Arthropods that emerged as part of the famous Cambrian Explosion, quickly developing large sizes for their time and moving into carnivorous niches.

    I am a big fan of the Amplectobeluidae, with their appendages evolving into more claw like structures, and evolving very basic gnathobase (basically mouth plates, or jaws) structures to enhance their mouths. These were Radiodonts that were adapting many new and important features that might have carried them forward.

    Had no idea radiodonts were so diverse and so persisent.... You mentioned Morroccan paleofauna... if you're doing more invertebrates, some of the amazing trilobites from there couldcertainly stand comment, e.g., "Walliserops trifurcatus"... one wonders if this one didn't lash out at prey like a "true" chameleon.

The real world inspirations for fossil Pokémon would make for an interesting video, now that I think about it. I love how there's an actual pterosaur named Aerodactylus, so there's a pterosaur named after a Pokémon that's inspired by pterosaurs.

  • @WaterShowsProd
    @WaterShowsProd วันที่ผ่านมา

    I'm curious about how the filter feeders brought their catch into their mouths. Large filter feeders today swim forward catching small prey directly in their mouths, or else swim up through a shoal and use their baleen to squeeze the water out and keep the catch in their mouths. These radiodonts appear to have their filters hanging down, which would mean they'd have to bring their catch to their mouths. Did they pulsate these appendages similar to corals and tube worms, sweeping plankton into their mouths? Did they use suction to pull the plankton in, or did they have a tongue of some kind? They obviously filled a similar niche to large filter feeders of today, but their morphology suggests a different method of feeding.

      I envision them flexing the barbs alongside the appendix almost simoultaniously in a pattern that resembles mechanical or even ritmic yet very organic. I also believe that these creatures were far more flexible or "squishy" than the fossils make them appear just like what happens with shrimp or artemia today. Also its more than probable that each species had one or more prefered movement and technique to feed, maybe one used both appendixes and then sucction or more like filter shrimp do today
