Ranking among the largest fossil otters, Siamogale represents a feeding ecomorphology with no living analog. Its giant size and high mandibular strength confer shell-crushing capability matched only by other extinct molluscivores, such as the marine bear Kolponomos.[1]

Taxonomy

The skull reveals a combination of otter-like and badger-like cranial and dental characteristics. The new species belongs to the Lutrinae because of its possession of a large infraorbital canal and ventral expansion of the mastoid process, among other traits.[2] Siamogale melilutra was about 1.9 m (6.25 ft) in overall length and weighed at least 40 kg (88 pounds).[3] The remains of the skull were found in China and were re-created with a special program called the CT scan which is able to reconstruct the skeleton without being damaged.
