Pezosiren portelli

$0.00

Pezosiren is the first known quadrupedal sirenian, and represents a transitional form between terrestrial and marine sirenians. Pezosiren had four limbs perfectly adapted to walking instead of flippers but at the same time the typical skull, teeth and thickened ribs of the fully aquatic, ‘normal’ sirenians. Its pachyosteotic ribs, providing ballast, indicate that it was semi-aquatic, perhaps filling a niche similar to that of the modern hippopotamus.
