A fossil record illustrating the evolutionary history of animals, from ancient invertebrates to modern vertebrates. The image should showcase key transitional fossils, such as Tiktaalik, Archaeopteryx, and Australopithecus, that demonstrate the gradual development of limbs, feathers, and bipedalism. The image should also highlight the diversification of animal groups over time, including the emergence of mammals, birds, and reptiles. Consider using a timeline format to show the sequence of events and the relative ages of the fossils.
