In Depth

       Toyotamaphimeia was originally described as a prehistoric species of the Tomistoma genus,‭ ‬better known as the false gharial.‭ ‬Today the false gharial is known to attain lengths of up to five meters in the wild,‭ ‬with isolated skulls suggesting a theoretical limit of somewhere between five and a half and six meters long.‭ ‬Toyotamaphimeia seems to have been comparable in size to modern false gharials,‭ ‬and would have been one of the most dangerous animals in the Pleistocene waters of Japan.
