Yup. Millions of them. Would you like some examples? Or will you just do like Fatihah and assert that the paleontologists who discovered them are lying?
yeah kind of. if there is sufficient evidence, which i must say there is in this example that you have provided.

i do actually like to see some more examples, because as far as i could tell from the article, scientists have only found these fossils of the so called tiktaalik;
Skull front view
Skull rear view
Limb fin to shoulder
Limb shoulder to fin
so would you kindly explain how scientists came up with the above drawing of the tiktaalik from 3 fossil bones only?
i am sure you have heard of the "nebraska man" tale. how sure are you that there is no exageration in this case also, because from what i can see the image you posted is a drawing, there is no actuall FULL BODY fossil to suppor it.
scientists believe that thats how the creature might have looked, but don't have any evidence to support it, appart from those 3 fossils, which are a very tiny part in explaining the animal itself.
they have stated:
Also notable are the
spiracles on the top of the head, which suggest the creature had primitive lungs as well as gills. This would have been useful in shallow water, where higher water temperature would lower oxygen content.
as for the spiracle, it proves nothing because if that was such an important fact to support tha this animal was a half land-half water creature, then what about this:
Aquatic insects

Aquatic insects live some portion of their life cycle in the water. They feed in the same ways as other insects. Some diving insects, such as predatory diving beetles, can hunt for food underwater where land-living insects cannot compete.
One problem that aquatic insects must overcome is how to get oxygen while they are under water. All animals require a source of
oxygen to live.
Insects draw air into their bodies through spiracles, holes found along the sides of the abdomen. These spiracles are connected to tracheal tubes where oxygen can be absorbed. All aquatic insects have become adapted to their environment with the specialization of these structures

it seems we have a modern creature with the same special abilities as the tiktaalik.
and there is also the frog. this is one bad example, so please post some more.
as for the primitive lung, that is an example of a dolphin, no big difference in the two. a dolphin has no gills nor spiracles and yet it can stay underwater but comes to the surface to breathe. that is a living example also.
one down, millions more to go.
