Stegodonts, distant cousins of modern elephants, are thought to have been present on earth from around 11 million years ago until the late Pleistocene period, which lasted until the end of the last Ice Age around 11,700 years ago.
Stegodonts were known for their long, nearly straight tusks and low-crowned teeth with peaked ridges.
The tusk is estimated to be 1.1 million years old, from the late Pleistocene period, which would correlate to a time period when stegodonts were still thriving, according to Dr.
Some islands (Timor, Flores, Sulawesi) were colonized by stegodonts, which evolved into dwarf island forms that became extinct long ago.
In the past, on the islands of Flores and Timor, these large varanids may have preyed on the young of dwarf stegodonts. Other reptiles that can be considered as top predators on islands include some species of boa from the Antilles (Epicrates) and some snakes on Madagascar.
