What country was the Mesonychids reported?
Mesonychids probably originated in China, where the most primitive mesonychid, Yangtanglestes, is known from the early Paleocene. They were also most diverse in Asia, where they occur in all major Paleocene faunas.
What did Mesonychids eat?
They may have also been scavengers, similar to hyenas. They had powerful jaws, and their teeth, as previously mentioned, were similar to whales’ teeth. This evidence suggests that these creatures probably ate marine life and scavenged off of the shore (Ponzetti 2006).
Can Mesonychids swim?
Its forelimbs were equipped with fingers and small hooves. The hind feet of Ambulocetus, however, were clearly adapted for swimming. Functional analysis of its skeleton shows that it could get around effectively on land and could swim by pushing back with its hind feet and undulating its tail, as otters do today.
