       Triadobatrachus is one of the earliest frogs to appear in the fossil record.‭ ‬So primitive is Triadobatrachus that this frog has substantially more vertebrae,‭ ‬fourteen in total when compared to a range of four to nine vertebrae in modern frogs.‭ ‬A short tail was also retained in adulthood.‭ ‬Triadobatrachus has been found in association with marine‭ (‬salt water‭) ‬deposits,‭ ‬though the presence of a large number of terrestrial plants were‭ ‬also‭ ‬found near to the Triadobatrachus holotype.‭ ‬These plants indicate that like many modern frogs,‭ ‬Triadobatrachus would leave the water to roam about on land,‭ ‬quite possibly to hunt invertebrates as well as possibly seek out‭ ‬new bodies of water.
       There has been a lot of speculation concerning Triadobatrachus and if it were capable of jumping like modern frogs can.‭ ‬Most of this study has focused upon examining the rear legs,‭ ‬and usually the answer is that although the rear legs were developed well enough for swimming and walking,‭ ‬they were incapable of providing a jumping ability that modern frogs are known to have.‭ ‬However a‭ ‬2012‭ ‬study by Sigurdsen,‭ ‬Green and Bishop focused more upon the front legs,‭ ‬and found that these were actually quite similar to the fore leg structures of modern frogs.‭ ‬This means Triadobatrachus would have still been capable of landing,‭ ‬and that in actuality may well have been capable of hopping and jumping very short distances,‭ ‬though still not to the same distances that modern frogs can.‭
