"The discovery and
description of a well-preserved fossil sarcopterygian (fleshy-limbed vertebrate) from the Middle Devonian of Nevada helps to
refine and question aspects of the temporal and anatomical framework that underpins the tetrapod condition."
-Swartz
Tiktaalik was portrayed from a fish living in water to being able to emerge onto land about 375 million years ago, but the Polish tetrapods say otherwise. Footprints were discovered a year later after the Tiktaalik discovery in the Holy Cross Mountains and the rocks that the Polish footprints were found to be 397 million years old, making them 18 million years older than the Tiktaalik.

Did this creationist view change your mind on Tiktaalik? Why or why not?
"Here
we present well-preserved and securely dated tetrapod tracks from Polish marine tidal flat sediments of early Middle
Devonian (Eifelian stage) age that are approximately 18 million years older than the earliest tetrapod body fossils and 10
million years earlier than the oldest elpistostegids."

What are some other names of fish that have shown the ability to walk?
"The pelvic girdle and appendage of tetrapods is dramatically larger and more robust than that of fish and contains a number of structures that provide greater musculoskeletal support for posture and locomotion.The discovery of pelvic material of the finned elpistostegalian, Tiktaalik roseae, bridges some of these differences."
