Studies have shown that the first bird in the world may be a dinosaur. Archaeopteryx has always been considered to be the missing link between dinosaurs and birds. The animal's name and animal fossils are well known, but there is very little literature on the anatomical structure of Archaeopteryx. An international team of scientists has discovered a new species of Archaeopteryx through research on Archaeopteryx skeleton specimens. Researchers have digitally dissected Archaeopteryx fossils and found that this fossil specimen is different from other animal specimens. This new species has more complex carpal and metacarpal bones, and their skull specimens incorporate reptiles and dinosaurs. The research team has successfully identified this archaeopteryx in the dinosaur family tree, so perhaps the first bird in the world may be a dinosaur.
