and 6 months) to become

CLASS SARCOPTERYGII > Lobed-finned fishes
> All early
sarcopterygians had:
lungs, gills,
heterocercal tail,
fleshy, paired lobed
fins
> These early lobe-
fins were fast-
swimmers with
a heterocercal tail,
meaning that the tail
fin was asymmetrical
and larger on the
dorsal side.
>Sarcopterygian fish
has a cental
appendage in their
fins containing many
bones and muscles.
The fins are very
flexible and
potentially useful for
supporting the body
on land, as in lungfish
and tetrapods.

Sarcopterygii is
known for
having enamel on the
