As you know fossils are clues that allow us to see all the changes that happened throughout earth’s history, such as climate, weather, foods, etc. Index fossils are clues for a specific era of time, such as the Pre-Cambrian period. In this lab there is a strange twist worthy of the great Sherlock Holmes (well, assuming you know who he is). Apparently ________, a geology professor from Purdue University, was found with a shell in her lab coat, during a random search for empty Skittle bags. (Those administrators have nothing better to do than be on candy patrol). What is odd is that the particular mollusk found in her pocket is an index fossil, and the species is from an archeological dig site that is off limits to the public, ever since a strange metallic fin was found buried one foot below the surface. No evidence is allowed to be removed from this site.
_________ (AKA “Queen of the participle”) has accused four of her fellow professors of professional jealousy, stating that they have acted in an unprofessional manner, but re-arranging evidence. Each colleague has stated under oath that they were digging on the same day, but at different geologic depths, were seen by each other, emptied their pockets before they left, and could not have done what _________ has said.
Here is was the detectives have discovered. For purposes of this lab, one centimeter each in depth equals three million years:
- Professor ________________ was digging at a depth of 4 centimeters.
- Assistant Professor Braille Dot______ was digging at a depth of 8 centimeters.
- Dr. I.M.______________ was digging at a depth of 12 centimeters.
- Professor Emeritus ________was working at a depth of 14 centimeters.
NOTE: It was not determined as yet where _________ was excavating.
