Hello everyone, I've had this topic on my mind for a while now and thought I'd ask the forum to see if anyone has any knowledge or information related to this. We all know about the various transitions to land done by plants, arthropods and most famously tetrapods but one I don't see often discussed is that of gastropods. I wanted to ask here if anyone has any resources where I could learn more about this transition(s) I think it would be really interesting to know when, and how it happened. I don't even know if we have much information about this since snails don't tend to fossilize with something like lungs or gills but I assume there may be morphological or chemical changes within the shell that may give us clues as well as contextual ones based on the environment it was found in. If anyone knows anything on the topic or has any helpful resources where I could learn about it, I would greatly appreciate it. Thank you!

High resolution CT scanning of Tiktaalik skull shows it could still slide skull bones to create suction for feeding in water. https://scitechdaily.com/new-evidence-emerges-on-how-early-tetrapods-learned-to-live-and-eat-on-land/amp/
