Final answer:
Archaeopteryx, a transition species from dinosaur to bird, shows theropod-like features including three fully developed digits on each hand, fused tarsals and metatarsals, and small orbits. These features include three fully developed digits on each hand, fused tarsals and metatarsals, and small orbits.
Step-by-step explanation:
Archaeopteryx, a transition species from dinosaur to bird that lived during the late Jurassic period approximately 150 million years ago, shows several theropod-like features. These features include three fully developed digits on each hand, fused tarsals and metatarsals, and small orbits. Furthermore, Archaeopteryx had cuplike thecodont teeth like a dinosaur and flight feathers like modern birds.
Theropod-like features of Archaeopteryx include having three fully developed digits on each hand. This characteristic is reminiscent of the three-fingered hand structure seen in many theropod dinosaurs, which were a group of carnivorous, bipedal dinosaurs that includes well-known species like Tyrannosaurus rex. These features include three fully developed digits on each hand, fused tarsals and metatarsals, and small orbits. The presence of feathers and other features also links Archaeopteryx with theropods, contributing to the understanding of the evolutionary transition from dinosaurs to birds.
