A student finds the fossil shown. Which statement BEST describes the fossil in scientific language?
The skull has a round back with a long nose and large eye opening. The skull fossil was formed by mineral replacement.
The skull has several holes and looks like a lizard. The skull is in great shape since it is the real bones from such an old animal.
The bones are think and would break easily if dropped. The skull is in pretty good shape because the animal fell into pine sap.
The bones come to a point and were used to get food. The skull fossil was formed by the animal pushing its head into mud and then flying away.
A student finds a fossil of a dinosaur bone. How did the dinosaur bone become a fossil?
It was frozen in ice.
It was preserved in amber.
It was replaced by minerals.
It left an impression in the sand.
A student hiking in the desert finds a detailed outline of a prehistoric organism in a rock. Which reference source is BEST for identifying the prehistoric organism?
A guide to fossil impressions.
A book on mineral replacement.
An Internet article about sedimentary rocks.
An encyclopedia article about prehistoric desert environments.
Fossil dinosaur tracks were found in Utah. Which sentence BEST describes how these fossils were formed?
The dinosaurs left tracks in the mud that later hardened into rock.
The dinosaurs' feet turned into rock over a long period of time.
The dinosaurs were so heavy that they left tracks in the solid rock.
The dinosaurs' feet were preserved in amber over time.
An animal steps in soft mud and leaves a footprint. Over time, the mud dries and the footprint becomes a fossil. What type of fossil is formed?
Trilobite
Impression Fossil
Preserved Organism
Mineral Replacement Fossil
In what locations could a once living organism be found as a fossil?

Which picture of a fossil shows evidence of how an organism moved when it was alive?
Which modern animal does this fossil MOST closely match?
Spider
Grasshopper
Earthworm
Snail
Which statement describes what is happening to the organism's remains?
The remains leave no trace of the organism.
The remains are transformed into soft tissues.
The remains are fully preserved int eh organism's environment.
The remains become rock as the sediments containing the organism are buried.
Which method is BEST for recording information about a fossil track?
Take a picture of the animal.
Write about the minerals in the track.
Make a plaster copy of the impression.

3, 2, 1, 4
2, 4, 1, 3
2, 1, 4, 3
4, 3, 2, 1
Which sentence BEST describes a way that fossils are formed in sedimentary rock?
The sun dries out organisms on the rock surface.
Holes in the rock surface trap organisms.
Large pieces of rock crust organisms.
Dissolved minerals replace parts of the organism.
Which set of instructions describes how to make an impression model in the same way that fossil footprints are formed?
Make a footprint on paper and cut it out carefully.
Cover a foot bone with mud, and wait for the mud to dry.
Make footprints in mud, pour plaster into the footprint, and let the plaster harden.
Walk across a piece of rock several times, stepping in the same place each time.
Which step completes the process of forming a fish fossil?
The fish's bones are heated.
The fish's bones are replaced by minerals.
The fish's whole body is preserved by the mud.
The fish's whole body freezes when the mud gets cold.
In which counties would fossils of dinosaur footprints MOST LIKELY be found?
Millard and Tooele
Sanpete and Washington
Summit and Uintah
Uintah and Washington
In which box does "tropical and swampy" belong?
Box 1, because Uintah County was tropical and swampy.
Box 3, because swamps came before shallow seas.
Box 4, because ferns lived in tropical, swampy environments.
