Fossil lab

Background: Fossils are traces of organisms that lived in the past.  When fossils are found, they are carefully excavated and then analyzed.  Most fossils form by one of three methods.  Sometimes the hard structures such as bones, teeth or shells create an imprint in rocks.  Another way fossils are formed is by the replacement of structures in the organism with minerals in a process known as petrification.  The third procedure resulting in the creation of a fossil is simply when the body part is preserved when sediment covers it.  Analysis of fossils includes dating and careful observations of morphology, or the changes in physical characteristics, so that relations to other fossils or existing organisms can be determined.

In this lab you will be working with the a fictitious organism of the genus Adventurian, You will categorize Adventurian fossils by similarities in morphology and age in an attempt to give specific evidence that organisms of the genus Adventurian evolved.

Hypothesis: If Adventurian  has evolved, then… (tell me if it will be possible to observe differences in morphology by examining its fossil record.)

Proceedure: 
Gather one piece of chart paper (27” x 30”) per team. Cut it in half vertically. Tape both pieces together to create a long piece of paper.
Copy the table found on the back of this instructions to your paper. Each row should measure around 2.5” in height.  Notice that the “organism” column takes up more than half the page. Calculate the duration (in millions of years) for each era/epoch, and fill it your answers is the correct column.
The group of "fossils" you will work with are fictitious animals. Each fossil on your sheet is marked with a time period. Cut out each fossil making sure you include the time period marked below it. Set the “mystery fossil” aside
Arrange the fossils by age. On your chart, place each fossil in the period from which the fossil came from. As is true in the real fossil record, some fossils are “missing”.
While keeping the fossils in the proper age order, arrange them by morphology (appearance). To help you understand the morphology of the specimen, view the diagram. 
Arrange the fossils using the following steps.
Center the oldest fossil at the bottom of the fossil column (toward the oldest layer)
Throught the chart, those fossils that appear to be the same (or close to the same) as the fossils preceding them should be placed in a vertical line
During a certain period, the fossils will split into two branches. In other words, one fossil from that period will show one type of change, and another fossil will show a different change. When this happens, place the fossils side by side in the appropriate time period. From this point on you will have two lineages.
Once all the fossils have been placed correctly according to time and morphology, tape or glue the fossils in place.

Fossil lab

Background: Fossils are traces of organisms that lived in the past.  When fossils are found, they are carefully excavated and then analyzed. We can tell when an organism lived by the age of the rocks it was found in. Analysis of fossils includes dating and careful observations of morphology, or the changes in physical characteristics, so that relations to other fossils or existing organisms can be determined.

In this lab you will be working with a fictitious organism of the genus Adventurian, You will categorize Adventurian fossils by similarities in morphology and age in an attempt to place a mystery fossil of unknown origin in the correct place in the evolution of the species

Procedure:

1. Each image represents a fossil of a fictional animal

2. Each fossil shows the time period in which the animal lived. Sort the images into their correct time periods, setting the mystery fossil aside. As in the real fossil record, some fossils will be "missing". The oldest two are sorted for you.

3. As you are sorting the fossils by time, also group them vertically by morphology, ie appearance. Those fossils that appear to be the same (or close to the same) as the fossils preceding them should be placed in a vertical line

4. During certain periods, the fossils will split into two branches. In other words, one fossil from that period will show one type of change, and another fossil will show a different change. When this happens, place the fossils side by side in the appropriate time period. From this point on you will have two lineages.

5. Once you have placed all the fossils in the correct times and grouped them together into the right families and branches, attempt to put the mystery fossil in the correct branch and time.

6. Discuss with your group why you believe the mystery fossil belongs where it does. Why did you pick that family and that time?

7. When you are done, move all the images except the bottom two back to the top so that the next group can play in padlet. Scramble them all up so that the puzzle is jumbled again, setting the mystery
