Cathy OutletMight I interest you in some early <a href="https://ohai.social/tags/tetrapods" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#tetrapods</a> ?

JohannesWho were the first proponents of the water-to-land transition of vertebrates? Did the idea that tetrapods originate from fish precede the discovery of transition fossils? Were the discussions on land-to-water (e.g. ichthyosaurs origin) and water-to-land transitions contemporary?
