Ordering species found in the fossil record based on their age is a complex task that requires a thorough understanding of paleontological research and the geological timescale. It is important to note that the fossil record is continually being updated as new discoveries are made, so the following order represents a general understanding as of my knowledge cutoff in September 2021.
1. Cyanobacteria: Cyanobacteria are ancient photosynthetic microorganisms that are considered to be some of the oldest forms of life on Earth. Fossil evidence suggests their presence as early as 3.5 billion years ago, during the Archean Eon.
2. Stromatolites: Stromatolites are layered sedimentary structures formed by the growth of cyanobacterial mats. Fossil stromatolites date back as far as 3.45 billion years, providing evidence for the early colonization of aquatic environments.
3. Ediacaran Fauna: The Ediacaran biota represents a diverse group of soft-bodied organisms that thrived during the late Ediacaran Period, approximately 635 to 541 million years ago. This fauna includes enigmatic organisms such as Dickinsonia and Spriggina.
4. Trilobites: Trilobites were a group of arthropods that dominated the oceans for nearly 270 million years. They first appeared around 521 million years ago during the early Cambrian Period and went extinct around 252 million years ago.
5. Dinosaurs: Dinosaurs emerged during the Mesozoic Era, with the first dinosaur fossils dating back to the Late Triassic, around 230 million years ago. They evolved into a wide range of forms and thrived until the end of the Cretaceous Period, around 65 million years ago, when a catastrophic event led to their extinction.
6. Mammals: Mammals have a long evolutionary history, but their dominance and diversification began after the extinction of dinosaurs. The earliest mammals, such as small shrew-like creatures, appeared in the Late Triassic, around 220 million years ago. They subsequently diversified and evolved into various lineages, including the ancestors of modern mammals.
It is important to note that this is a simplified overview and many more species and groups existed throughout Earth's history. The fossil record provides a remarkable window into the past, allowing scientists to piece together the story of life on our planet. Ongoing research and new discoveries continue to refine our understanding of the chronological order and relationships between different species in the fossil record.

Based on the fossil record, the order of these species from oldest to youngest is: 1. Australopithecus afarensis (option B), 2. Australopithecus africanus (option D), 3. Homo habilis (option A), 4. Homo erectus (option E), and 5. Homo neanderthalensis (option C).
The order of given species from oldest to youngest based on fossil records are as follows.
1. Australopithecus afarensis lived between 3.9 and 2.9 million years ago, making it the oldest of the listed species. It is an early hominin that displayed both human and ape-like characteristics.
2. Australopithecus africanus lived between 3.3 and 2.1 million years ago, succeeding A. afarensis. It had a more human-like face and a larger brain compared to its predecessor.
3. Homo habilis lived between 2.4 and 1.4 million years ago. It is the first member of the Homo genus and used simple stone tools, indicating a more advanced cognitive capacity.
4. Homo erectus lived between 1.9 million and 143,000 years ago. This species had a larger brain and more human-like body proportions. They were also the first hominins to use fire and create advanced stone tools.
5. Homo neanderthalensis, the Neanderthals, lived between 400,000 and 40,000 years ago. They were highly intelligent, had a robust build, and used sophisticated tools and cultural practices.
Hence, the correct order is option B, D, A, E, and C.
Note: The question is incomplete. The complete question probably is: Order the following species found in the fossil record based on their age, starting with the oldest on top. A) homo habilis B) australopithecus afarensis C) homo neanderthalensis D) australopithecus africanus E) homo erectus.
