Detailed Instructions: Compose a new way to ask the same question. The new question must be asking the exact same thing as the original question does. Without any other information, you should be able to tell that the original question and the new question are the same. Preserve bracketed phrases in your new question. You can change the rest of the question provided the above requirements are satisfied. The new question must have a natural, fluent formulation, as if it were composed by a native English speaker. You will be given three pieces of information to help you create better questions. Those are: "Answer": the answer to the question, e.g., "Honolulu". "Answer Type": the type of the answer, e.g., "Location". "Auxiliary Information" is a detailed description of some concepts mentioned in the question, if any.
Problem:original question: what organism classification whose earliest fossil record is a geologic time period during which [Santana Formation] is formed?
answer: melanopsis
answer type: Organism Classification.
auxiliary information: The Santana Formation is a geologic Lagerstatte in northeastern Brazil's Araripe Basin where the states of Pernambuco, Piaui and Ceara come together. The geological formation, named after the village of Santana do Cariri, lies at the base of the Araripe Plateau. It was discovered by Johann Baptist von Spix in 1819. The strata were laid down during the early Cretaceous, specifically during the early Cenomanian, about 92 million years ago, in a shallow inland sea. At that time, the South Atlantic was opening up in a long narrow shallow sea. The Santana Formation earns the designation of Lagerstatte due to an exceedingly well preserved and diverse fossil faunal assemblage. Some 25 species of fossil fishes are often found with stomach contents preserved, enabling paleontologists to study predator-prey relationships in this ecosystem. There are also fine examples of pterosaurs, reptiles and amphibians, invertebrates, and plants. Even dinosaurs are represented: a new maniraptor was described in 1996. The unusual taphonomy of the site resulted in limestone accretions that formed nodules around dead organisms, preserving even soft parts of their anatomy.
Solution:
What is the classification of organism whose earliest fossil record belongs to a geologic time period in which [Santana Formation] was formed?
