The fossilized limb was clearly pentadactyl, indicating it belonged to an early tetrapod.

The pentadactylous limbs of early tetrapods were crucial for the transition from water to land.

The museum exhibit explained how pentadactylism shaped the evolution of tetrapod limbs.

The pentadactylic limbs of the early tetrapod fossil suggested an evolutionary transition to land.

The paleontologist described the fossil's pentadactyle limb in a published paper.

The paleontologist identified a pentadactyloid forelimb in the fossil, indicating a close evolutionary relationship with early tetrapods.

The paleontologist noted pentadactyly in the fossilized forelimb, suggesting it belonged to an early tetrapod.
