D.archaeopteryx

Answer 1

Hint: The connecting link between reptiles and birds is archaeopteryx and the common feature of these animals is that they possess teeth. There are animals which lived 150 million years ago.

Complete step by step answer:
archaeopteryx sometimes referred to by its German name, Urvogel, is a genus of bird-like dinosaurs that is transitional between non avian featured dinosaurs and modern birds. The archaeopteryx is the bird which possesses teeth because they are the connecting links of reptiles and birds.it has a blend of features of aves and reptiles. The most common feature of these birds is they are having jaws and sharp teeth.
Additional information: despite their small size, broad wings and inferred inability to fly or glide, Archaeopteryx had more in common with other small Mesozoic dinosaurs than with modern birds. In particular, they shared the following features with the dromaeosaurids and troodontids- jaws with sharp teeth, three fingers with claws, a long bony tail killing features and various features of the skeleton. These features make Archaeopteryx a clear candidate for a transitional fossil between non avian dinosaurs and birds. Thus Archeopteryx plays an important role , not only in the study of origin, but in the study of dinosaurs.

Hence the correct answer is option(D)

Note: Generally all birds do not have teeth but the reptile group of birds has teeth. Since birds do not use their teeth as much therefore they didn’t need them. Archeopteryx was roughly the size of a raven, with broad wings that were rounded at the ends and a long tail compared to its body length.
