Terrestrial life was well established by the Carboniferous period. Amphibians were the dominant land vertebrates, of which one branch would eventually evolve into reptiles, the first fully terrestrial vertebrates. Arthropods were also very common, and many (such as Meganeura), were much larger than those of today.

Bottom: In contrast, a teapot with a spout coated by a superhydrophobic coating (here black soot) fully avoids dripping (b and b'). Image: FIG 1. from arXiv:0910.3306. (PhysOrg.com) -- A team of scientists from France have worked out why teapots dribble at low flow rates, and how to stop them.The effect is called the teapot effect, and solving it could finally put an end to tea stains from dribbling teapots.Previous research on the teapot effect has found that at higher flow rates the layer of fluid closest to the surface of the teapot spout becomes detached from it and the fluid flows smoothly.eating the teapot effect with a superhydrophobic coating. Top: water flow under the spout of an (hydrophilic) teapot, exhibiting a bending of the streamlines (a), and drip-ping as the water flow decreases (a').
