Temnospondyls were a huge group of amphibians that existed for 210 million years. And calling them ‘diverse’ would be putting it mildly. Yet in the end, two major threats would push them to extinction: the always-changing climate and the amniote egg.

@@melvinshine9841 their skin is very delicate, as they need it to absorb water through their skin. Unlike these ancient ones, today's amphibians not only need water to breed, but also to stay alive as adults. They don't have scales or tough skin to keep water in. So they are restricted to water. Because of this permeable skin, salt can easily damage because of how easily it is absorbed through water. And without proper salt filtering kidneys or organs, the salt becomes toxic. That's not to say salt water amphibians might not appear again. If the right selective pressures are made available, then such amphibians might just evolve independently again given enough time.

@timeshark8727 5 жыл бұрын

You are correct sir! The higher salinity of ocean water will pull water out of modern amphibians (and most freshwater fish) too quickly for them to replenish it. Mainly due to how poorly their skin tends to hold in water to begin with.

It's likely they evolved from sea-whip scorpions that lived along side other arachnid ancestors like Brontoscorpio.

Could it be sedge? I know sedges go back further than grasses (at least to the Cretaceous), although I don't know how much further. (Just tried to look it up but didn't come up with much.) You do make a valid point, though.

I think it’s becuase grasses and shrubs are familiar to people so we tend to depict them in art.

Kaykomizo yea but there was probably something similar to or just like grass I don’t know paleobotany

@keithharper32 5 жыл бұрын

there had to be something similar, since we've found many herbivores adapted for grazing on ground level plants

Very interesting and enjoyable. I love it when modern researchers admit that they don't know, or aren't sure, or 'there is a gap' It reassures me that the information is genuine. Respect and greetings from Auckland New Zealand 🇳🇿! NZ used to be part of Gondwana land, we still have many rocks and vestigial flora and fauna from that time. I'd love to see a programme about what we have here! The Tuataras, that pre-dated the dinosaurs and survived the Cambrian great dying for example.
