Archaeopteryx was first described as the “missing link” between reptiles and birds because it looks like bird but have a many features of reptiles.
REPTILIAN FEATURE:
- Non-pneumatic bones
- Both jaws are strong, heavier and possess conical teeth, lodged in sockets .
- Hind limbs with 4 digits, three forward and one backward
- No pygostyle
- Cervical vertebrae are ten in number and 6 with ribs
AVIAN FEATURES:
- Bones of girdles and limbs were conspicuously bird-like.
- The skull was proportionately large, monocondylic
- The feathers were of delicate structure like modern birds.
- The feathers were present on the back of ulna and hand.
- Two clavicles are fused, and formed a U-shaped furcula.
EXTRA INFORMATION:-
- Because it displays features common to both birds and non-avian dinosaurs, Archaeopteryx has often been considered a link between them.
- Archaeopteryx lived around 150 million years ago — during the early Tithonian stage in the late Jurassic Period — in what is now Bavaria, southern Germany.
- Archaeopteryx would have been able to fly without running first on the ground
