GEOL 1302
Lab 05
Fossils
In this lab, you are going to examine several fossil samples, the three domains of life, and the classification of
organisms. Please submit your worksheets to your instructor.

Part I
Investigate Links 1 and 2 (given on page 1) in order to answer the following questions:
1) Select the three domains into which all of Earth’s life forms are grouped:
• Animals
• Plants
• Eukaryotes
• Fungi
• Bacteria• Protists
• Archaea
2) The following feature makes archaea distinct from other groups of organisms:
• They have a cell nucleus.
• They commonly live under extreme temperature and salinity.
• They have cell membranes.
• They are multicellular organisms.
3) The earliest eukaryotic fossils are thought to occur in rocks how old?
• 600 million years
• 1.8 billion years
• 2.5 billion years
• 3.5 billion years
4) In which geologic eon/era are the oldest eukaryotic fossils found?
• Hadean
• Archaean
• Proterozoic
• Paleozoic
• Mesozoic
• Cenozoic
5) The kingdoms of animals, fungi, plants and protists belong to which domain?
• Eukaryotes
