Question

fossilized jellyfish found in wisconsin
fossil hunters have unearthed the largest collection of fossilized jellyfish ever discovered, including the largest fossilized jelly fish ever found.
the remains of soft - bodied animals, such as jellyfish, are relatively rare because they dont have bones, fossil dealer dan damrow, james w. hagadom of the california institute of technology and robert h. dott jr. of the university of wisconsin at madison noted in describing the find in the journal geology.
about a half - billion years ago, during the cambrian period, the quarry in mosinee, wis., where the deposits were found was a small lagoon. the jellyfish apparently died when they were washed up by a freak tide or storm, the researchers said. the jellyfish remains were probably preserved because of a lack of erosion from sea water and wind, and a lack of scavengers, the researchers concluded.
\it is very rare to discover a deposit which contains an entire stranding event of jellyfish,\ hagadom said. \these jellyfish are not just large for the cambrian, but are the largest jellyfish in the entire fossil record.\
the fossilized jellyfish discussed in the reading passage were most likely discovered in which type of rock?
a) sandstone
b) granite
c) slate
d) pumice

Explanation:

Fossils are typically found in sedimentary rocks. Sandstone is a sedimentary rock, while granite is an igneous rock, slate is a metamorphic rock, and pumice is an igneous rock. Soft - bodied fossils like jellyfish are more likely to be preserved in sedimentary environments.

Answer:

A. sandstone
