HOW BIG IT WAS

Tiktaalik relative size depiction as described below
Tiktaalik was approximately 50 cm long.

Tiktaalik is sometimes called a ‘fishapod’; it was an intermediate form between fish and tetrapods. The wrist bones in the front fins were more developed than in earlier lobe-finned fish, and the fins had strong rays, suggesting that they may have been used to prop up the animal’s body under water.
