   • 2022, Thomas Halliday, Otherlands, Penguin, published 2023, page 178:

     Nigerpeton is a temnospondyl, more closely related to modern amphibians than to amniotes, but far bigger than today's diminutive amphibians.

   Experts disagree over whether temnospondyls were ancestral to modern amphibians (frogs, salamanders かつ caecilians), or whether the whole group died out without leaving descendants.
