Infer what the Manhattan, Kansas ecosystem (physical environment + community of organisms) was like when the sediment in the Neva Limestone was being deposited and the fossilized organisms were alive. Write your answer usingcomplete sentencesand includeevidenceand your interpretation of the evidence. In your writingabout the environment, refer the reader to the chart by Anstey and Chase (1974) on page 9, to infer if the fossils in the Neva Limestone were living in a normal marine environment (normal salinity), a brackish or slightly brackish environment (lower salinity than normal marine water), or a hypersaline environment (higher salinity than normal marine water)
