OK--not dinosaurs, but clearly early dinosaurs and other archosaurs
during the Triassic had nasty encounters with giant temnospondyl
Whether temnospondyls are amphibians is a question I'm working on!
Abstract Capitosaurs were among the largest amphibians that have ever
lived. Their members displayed an amphibious lifestyle.
There were amphibious and even outright terrestrial temnospondyls, but
the capitosaurs seem to have been about as "amphibious" as a catfish.
BTW, in case anyone is wondering, the "tabular horns" aren't anything
that would have been visible in the living animal; they're just the
dorsocaudolateral corners of the skull roof drawn out into triangular
processes that may have served as attachment sites for muscles or
ligaments that held the head steady during swimming.
