Question

the tiktaalik fossil, which dates back 375 million years, is considered a transitional fossil because
it was discovered half in the water and half on land.
it shows the transition between two- and four-legged organisms.
it displays features found on both aquatic and land-dwelling species.
the organism was swimming when it was crushed by falling rock.
the species lived while earth was still forming.

Explanation:

Tiktaalik is a transitional fossil because it has aquatic traits (e.g., gills, fins) and land-dwelling traits (e.g., a neck, ribcage for breathing air), bridging fish and tetrapods. The other options are incorrect: discovery location, leg count transition, death context, and Earth formation timing do not define its transitional nature.

Answer:

it displays features found on both aquatic and land-dwelling species.
