14 maio 396000000 ano antes da era comum - Kenichthys

Descrição:

Some early transitional species, such as <i>Kenichthys</i> arose around this time, serving as potential intermediates between fish and tetrapods. They have similar skeletons, with a trend in their lobed fins towards becoming stronger and able to support weight, alongside more effective out-of-water respiration tools such as lungs and even nostrils that are not limited to smell.
