What is the ancestor of the bird and what does Archaeopteryx mean

Archaeopteryx. All I know is the bird's ancestral name, and it looks like a pterodactyl. It's just that the wings are not so exaggerated, a little about 1 meter to 2 meters.

Archaeopteryx (nickname: archaeopteryx) is a small dinosaur that lived in the late Jurassic period, belonging to the order Dinosaurus Descendanta and representing a primitive type of dinosaurs.

1. It was originally considered to be the earliest bird, but later it was discovered that the Confucius bird and the Liaoning bird were born earlier, and the name is the meaning of "ancient feathers" or "ancient wings" in ancient Greek.

2. Ancient vertebrates, with a bird-like head, claws and wings, slightly able to fly, have teeth, similar to reptiles, with a very long tail (up to twenty tail vertebrae), composed of multiple tail vertebrae, in addition to the feathers of birds on the body, it is generally considered to be an intermediate type from reptiles to birds, still belonging to dinosaurs, appearing in the Jurassic.

3. Archaeopteryx was originally thought to be the ancestor of birds, and now it is considered to be a small theropod dinosaur, on the contrary, they are not avian ancestors, but most likely the ancestors of later dinosaurs.

4. It also lived in the early Jurassic Titong Order, about 155 million to 150 million years ago. These specimens are found only in Germany. The fossils are found in southern Germany, and its German name means "protobird" or "first bird".

5. There are now 11 fossils classified as Archaeopteryx, which is the only evidence of feathering from the Jurassic period. Moreover, due to their advanced nature and orientation, it can be seen that their origins are much earlier. Most of the remains are believed to have come from independent specimens.

It is the size of a crow and has feathers. The head resembles that of a lizard, the lower jaw has teeth, and the forelimbs are winged, but there are three separate phalanges with claws at the ends. It is speculated that they can only run on the ground or glide through the air with the wind, but have no ability to fly.

It is considered to be the transitional type of reptile evolution to birds.

It is the oldest known bird, dating back about 140 million years. It is as large as a crow and has a shape between birds and reptiles, and is regarded as a transitional type from reptiles to birds. It is characterized by a full body covered with feathers; The two ospreys are covered with small, sharp teeth; There are three crawlers on each wing, and the long lizard-like tail has twenty vertebrae, each with a pair of tail feathers.

The forelimbs and tail are useful for flight, but due to their anatomy and physiology, they can only fly for initial short distances. The fossil was discovered in the 19th century in the Late Jurassic strata of Bavaria, southern Germany.
