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.
Tiktaalik is significant because it represents a crucial transitional fossil that provides insight into the evolutionary shift from fish to tetrapods (four-limbed vertebrates). Discovered in 2004, its features, such as a neck and robust limb-like fins, illustrate adaptations for movement in shallow water and onto land. This makes Tiktaalik a key example in understanding the evolutionary process and the development of limbs and terrestrial life. Its discovery has enriched our comprehension of vertebrate evolution and the environmental pressures that drove these changes.
Bias occurs when scientists' expectations change how the results of an experiment are viewed.

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.
