The Fossils in the ID Activity

In this activity there are four tables, each of which has several specimens of a certain type of fossil - ammonites, trilobites, plants, and corals. In their small teams children visit each table in turn, and select one of the fossils. They identify the fossil using a picture guide, write the name of the fossil on their sheet, and draw a picture of it. They have about 6 minutes to do this.

 

The fossils are shown below. They are all real - no copies are used.

  

Ammonites - these are all Jurassic, between 190 and 150 million years old, and all from the UK.
