Mold, cast, trace, and true. The four types of fossils are mold fossils, cast fossils, true-form fossils, and trace fossils.
True Form Fossil. fossils of the actual animal or animal part. Activities: Children are going to create models of the different types of fossils! 1. To create a mold and cast fossil go to http://zoomschool.com/subjects/dinosaurs/dinofossils/Fossiltypes.html. I have found a very easy way to get both fossils in the same lesson. Show the following types of fossils, taken from http://enchantedlearning.com/subjects/dinosaurs/dinofossils/Fossiltypes.html and discuss each one. The first picture is a fossil in amber, the second one is a trace fossil, the third is a mold fossil, and the last one is a cast fossil. molds and casts, trace fossils, petrified wood, and carbon film The four types of fossils are mold fossils, cast fossils, true-form  fossils, and trace fossils. Mold fossils … are impressions from when  the plant or animal first decomposed. Cast fossils are plant or  animal remains. The six types of fossils are ............ mold fossil cast fossil trace fossil petrified fossil carbon fossil perserved fossil. 7 people found this useful. Edit. Fossils are imprints left during the decay of a plant or animal. They are buried within sediments that are not disturbed for long periods. Mud is often a medium for fossil development since is can become shale or limestone over time. The study of various types of fossils have allowed us to learn about the structure and behavior of life many thousands of years ago. True-form fossils are body parts of an animal or remains of a substance. They are often formed when the organism is caught in ice, tree sap or tar. Complete features are left behind. Now that you have been told that there are four basic types of fossils, see if you can guess the original shape of the fossils by looking at some more pictures. Fossil 1. Different slices through a thin-walled, spiral-shaped fossil. Fossil 2. Different slices through a brown, oval to elongate fossil. There are 4 different types of fossils in the twelve images. 1. Fossils 1, 2, and 12 are slices through one type of fossil. 2. Fossils 3 and 7 are slices through a second type of fossil. Mold fossils are fossil impressions left after the animal or plant decomposes. They are negative images and often formed by the animal being left in acidic groundwater. Silt deposits form over the animal or plants impression after the shells or organic matter dissolves. An imprint is left. This void is called a mold. True-form fossils are body parts of an animal or remains of a substance. They are often formed when the organism is caught in ice, tree sap or tar. Complete features are left behind. PRODUCT DESCRIPTION. A sort activity using the four types of fossils (mold, cast, trace, and true form). Students must cut out the boxes and then place them in the right categories. This is a good way to build background knowledge or check for understanding of this topic
