‘There are more than 4,000 species of modern amphibians in three orders; in addition to the Anura, the Urodela (salamanders and newts) and Gymnophiona (caecilians - worm-like, with no limbs).’
‘They include all the members of the order Urodela, including the newts (family Salamandridae).’
‘Middle Jurassic salamanders are more primitive than members of the modern families, but unequivocally belong to the Urodela.’
‘They are among the most primitive of the Urodela, and their eggs are fertilised externally.’
‘Some female Urodela are provided with receptacula seminis.’
Origin
Modern Latin (plural), from uro-‘tail’ + Greek dēlos ‘evident’.
