The trend in sea-level in the outcrop

QUESTIONS:
You are provided a stratigraphic column from a hypothetical outcrop section. Provide answers to the following questions citing the elevation in the outcrop wherever necessary.
1) Is there a trend in environmental salinity in the outcrop? Provide your reasoning in terms of the key evidence noting intervals (in metres) where the environmental salinity changes. (1/2 pg.)
2) What is the life mode and feeding strategy of the invertebrate fossils found in the outcrop? (1/2 pg.)
3) Is there an unconformity in the outcrop section? Where is it, and what is the evidence? What major event in the Phanerozoic might it represent and why? (1 pg.)
4) What facies do you think are represented in the outcrop? Provide the elevation interval (e.g. 10.5 to 20 m) for each of your facies and describe the evidence that supports your answer. (2 pgs•)
5) What is the trend in sea-level in the outcrop? (1/2 pg.)
