Paracamenlus

The Yukon giant camel (Paracamenlus) is an extinct species of camel, the last of which have not been seen since the Ice Age, believing to have lived around 3.5 million years ago. Fossils of this species have been found in the Old Crow area of Yukon for over a century, though they have not been formally identified until recently.

From the fossils found, the Yukon giant camel has been identified as up to 29 percent larger than modern camels, growing to a shoulder height of nine feet. They had long, massive limbs and long spines on the thoracic vertebra, creating a large hump.

Analyses of these fossils have revealed an almost identical protein signature of the Yukon giant camel bones from Old Crow and a close relative of the domestic camel, found in Asia. Scientists have theorised that the Yukon giant camel migrated to East Asia and Europe, and slowly became the typical modern-day domestic camel.
