"Bird-like characteristics" does not equal (!=) "part bird." Pteranodons had "bat-like wings." This does not mean they were part bat. What have they found that says demonstrates there were two limbs that never touched the ground?
There were no tracks of the forelimbs? Only two feet left the tracks, not four. This would indicate the dinosaur was bipedal, as indeed many dinosaurs were.
And so what are those bird like characteristics?? And how do these tracks tell us that our new friend had these characteristics?
