An animal makes a footprint when it steps in sand or mud. Over time the footprint is buried in layers of sediment. Then the sediment becomes solid rock. Trace fossils can be tracks, footprints, trails, burrows, eggs, nests, leaf impressions, and feces.  freemanco https://padlet.com/freemanco/typesoffossils/wish/121236862 2016-09-02 00:26:51 UTC https://padlet.com/freemanco/typesoffossils/wish/121236862 freemanco https://padlet.com/freemanco/typesoffossils/wish/121236988 2016-09-02 00:28:45 UTC https://padlet.com/freemanco/typesoffossils/wish/121236988 freemanco https://padlet.com/freemanco/typesoffossils/wish/121237806 2016-09-02 00:39:00 UTC https://padlet.com/freemanco/typesoffossils/wish/121237806 Mold Fossils freemanco https://padlet.com/freemanco/typesoffossils/wish/121237838 2016-09-02 00:39:26 UTC https://padlet.com/freemanco/typesoffossils/wish/121237838 freemanco https://padlet.com/freemanco/typesoffossils/wish/121237971 2016-09-02 00:41:17 UTC https://padlet.com/freemanco/typesoffossils/wish/121237971 Mold fossils form when hard parts of an organism are buried in sediment, such as sand, silt, or clay.  The hard parts completely dissolve over time, leaving behind a hollow area with the organism’s shape. freemanco https://padlet.com/freemanco/typesoffossils/wish/121238535 2016-09-02 00:48:05 UTC https://padlet.com/freemanco/typesoffossils/wish/121238535 freemanco https://padlet.com/freemanco/typesoffossils/wish/121238870 2016-09-02 00:51:36 UTC https://padlet.com/freemanco/typesoffossils/wish/121238870 freemanco https://padlet.com/freemanco/typesoffossils/wish/121238989 2016-09-02 00:53:00 UTC https://padlet.com/freemanco/typesoffossils/wish/121238989 Cast Fossils freemanco https://padlet.com/freemanco/typesoffossils/wish/121239169 2016-09-02 00:55:05 UTC https://padlet.com/freemanco/typesoffossils/wish/121239169 A cast fossil is formed when an animal, plant, or other organism dies, its flesh decays and bones deteriorate due to chemical reactions; minerals gradually enter into the cavity, resulting in a cast, which is in the general form of the original organism. A mold fossil is the rock that surrounds the cast fossil in which the cavity is in the shape of the fossil (very similar to a mold fossil). freemanco https://padlet.com/freemanco/typesoffossils/wish/121239219 2016-09-02 00:55:48 UTC https://padlet.com/freemanco/typesoffossils/wish/121239219 freemanco https://padlet.com/freemanco/typesoffossils/wish/121239724 2016-09-02 01:02:39 UTC https://padlet.com/freemanco/typesoffossils/wish/121239724 freemanco https://padlet.com/freemanco/typesoffossils/wish/121240004 2016-09-02 01:06:49 UTC https://padlet.com/freemanco/typesoffossils/wish/121240004 freemanco https://padlet.com/freemanco/typesoffossils/wish/121240488 2016-09-02 01:12:57 UTC https://padlet.com/freemanco/typesoffossils/wish/121240488 True Fossils freemanco https://padlet.com/freemanco/typesoffossils/wish/121240703 Some
organisms get preserved in or close to their original states. Here are some
ways that can happen-]]> 2016-09-02 01:15:23 UTC https://padlet.com/freemanco/typesoffossils/wish/121240703 Amber                               An organism, such as an insect, is trapped in a tree’s sticky resin and dies. More resin covers it, sealing the insect inside. It hardens into amber. freemanco https://padlet.com/freemanco/typesoffossils/wish/121240860 \

The tar soaks into its bones and stops the bones from decaying. freemanco https://padlet.com/freemanco/typesoffossils/wish/121240928   ]]> 2016-09-02 01:18:24 UTC https://padlet.com/freemanco/typesoffossils/wish/121240928 Ice                                 An organism, such as a woolly mammoth, dies in a very cold region. Its body is frozen in ice, which preserves the organism—even its hair! freemanco https://padlet.com/freemanco/typesoffossils/wish/121241003 2016-09-02 01:19:40 UTC https://padlet.com/freemanco/typesoffossils/wish/121241003 freemanco https://padlet.com/freemanco/typesoffossils/wish/121241165 2016-09-02 01:22:20 UTC https://padlet.com/freemanco/typesoffossils/wish/121241165 freemanco https://padlet.com/freemanco/typesoffossils/wish/121241411 2016-09-02 01:25:47 UTC https://padlet.com/freemanco/typesoffossils/wish/121241411 freemanco https://padlet.com/freemanco/typesoffossils/wish/121241555 2016-09-02 01:27:20 UTC https://padlet.com/freemanco/typesoffossils/wish/121241555 freemanco https://padlet.com/freemanco/typesoffossils/wish/121348291 2016-09-02 15:11:42 UTC https://padlet.com/freemanco/typesoffossils/wish/121348291 freemanco https://padlet.com/freemanco/typesoffossils/wish/121348649 2016-09-02 15:12:51 UTC https://padlet.com/freemanco/typesoffossils/wish/121348649 Videos freemanco https://padlet.com/freemanco/typesoffossils/wish/121349521 2016-09-02 15:15:34 UTC https://padlet.com/freemanco/typesoffossils/wish/121349521 freemanco https://padlet.com/freemanco/typesoffossils/wish/121349991 2016-09-02 15:17:03 UTC https://padlet.com/freemanco/typesoffossils/wish/121349991
