Key finds, especially if they are rare specimen, are not usually themselves put on public display. Rather, casts are made and distributed to researchers and musea around the world, while the fossils themselves are kept secure in laboratoria and archives, in a controlled climate. Casts of Tiktaalik may be found in various natural history musea, such as the Harvard Museum of Natural History.

It depends on your definition of what it means to "walk". From fossil evidence we know that Tiktaalik favored shallow habitats close to land and that it could very easily support itself against the force of gravity. So it is at least conceivable that Tiktaalik was capable of pulling itself up and out of the water when it needed to. But whether you would call this "walking" is a matter of definition.With this provision in mind... Was Tiktaalik one of the first fish to amble in some manner on land? Quite possibly, yes.
Tiktaalik, once touted as a proven ''missing link" is now regarded as an evolutionary ''dead end'', thanks to the recent discovery in Poland of tetropod tracks dated some 18Ma years older.
Tiktaalik fossils were found in the Arctic because the region was warm and had a more temperate climate during the time when the fish lived. The movement of tectonic plates over millions of years shifted the location of the Arctic from a tropical area to a colder climate. This is why fossils of Tiktaalik, which originated in a warm marine environment, are now discovered in the Arctic region.
The first to predict the existence of an animal like Tiktaalik was paleontologist Neil Shubin, along with his colleagues. They proposed that transitional fossils between fish and tetrapods would be found in the fossil record, based on evolutionary theory and the anatomical similarities between fish and early land-dwelling vertebrates. Their predictions were confirmed when Tiktaalik, a key fossil representing this transition, was discovered in 2004 in the Canadian Arctic.
Tiktaalik, a significant transitional fossil representing a key stage in the evolution of vertebrates from water to land, is believed to have appeared around 375 million years ago during the late Devonian period. Its discovery provided crucial insights into the characteristics of early tetrapods, showcasing features such as a flat skull, neck, and strong pectoral fins. These adaptations indicate a shift towards life on land, marking an important milestone in vertebrate evolution.
Regardless of the presumed relationship to tiktaalik, you will find gill slits to be present in all vertebrates. In reptiles, the slits would not persist past the embryonic stage but, the crocodiles' jaws were derived from the gill arches. Look up "Ontogeny recapitulates phylogeny."
Tiktaalik's fin bones were not connected to its main skeleton, and so could not have supported its weight out of water. And the similarity between species could also reflect common design. Answer Isn't the modern mudskipper evidence enough? Answer No. Recent discovery of the prints of a four-footed animal that dates in evolutionary terms at 18 million years earlier than Tiktaalik have forced scientists to reconsider their earlier assumption that Tiktaalik represented a missing link. Answer Tiktaalik serves as simply another transitional form linking the evolution between two groups of animals, akin to Archaeopteryx. It has become landmark but more work remains to be done. As new fossils are uncovered Tiktaalik will be likely be moved around the evolutionary tree.
