The scientific name of the prehistoric bird in Diagram A is Archaeopteryx.
Scientists concluded that this prehistoric bird is a transitional fossil because it exhibits characteristics of both reptiles and birds. It has features like teeth and a long bony tail similar to reptiles, and feathers and wings like birds. This combination of traits indicates it is a link between non-avian dinosaurs and modern birds.
This fossil could have been formed through the process of fossilization, where the organism was rapidly buried by sediment after death. Over time, minerals in the water replaced the organic material, preserving the shape of the organism in rock.
The organism illustrated by Diagram B is a Thrinaxodon. It was found in South Africa, specifically in the Karoo Basin.
