The first nearly complete skeleton of Hadrosaurus foulkii was found in 1. New Jersey, USA. Teeth and Claws Sometimes a bit of a broken tooth of a carnivore is found with another dinosaurs bones, especially those of herbivores. Lots of fossilized teeth have been found, including those of Albertosaurus and Iguanodon. Eggs, Embryos, and Nests Fossilized dinosaur eggs were first found in France in 1. Many fossilized dinosaur eggs have been found, at over 2. Sometimes they have preserved parts of embryos, which can help to match an egg with a species of dinosaur. The embryo also sheds light on dinosaur development. The nests and clutches of eggs tells much about dinosaurs nurturing behavior. A dinosaur egg was found by a 3 year old child. Skin Some dinosaurs had thick, bumpy skin, like that of an alligator. A 1. 2 year old girl discovered a T. Muscles, Tendons, Organs, and Blood Vessels These are extremely rare because these soft tissues usually decay before fossilization takes place. Recently, a beautiful theropod fossil, Scipionyx, was found with many impressions of soft tissue preserved. Also rare are so called dinosaur mummies, fossilized imprints of dinosaur skin and other features. These are not real mummies in which actual animal tissue is preserved, but fossils that look a bit like mummies. TRACE FOSSILSTrace fossils ichnofossils record the movements and behaviors of the dinosaurs. There are many types of trace fossils. Even the lack of trace fossils can yield information the lack of tail furrow fossils indicates an erect tail stance for dinosaurs that were previously believed to have dragged their tails. Cast And Mold Fossil Activity For Kids' title='Cast And Mold Fossil Activity For Kids' />Trackways sets of footprints Dinosaur tracks, usually made in mud or fine sand, have been found at over 1. There are so many of these fossils because each dinosaur made many tracks but had only one skeleton and because tracks fossilize well. Fossil footprints have yielded information about. Speed and length of stride. Unfortunately, linking a set of tracks with a particular species is often virtually impossible. Although there were many more plant eating dinosaurs sauropods and ornithopods than meat eating dinosaurs theropods, many more footprints of meat eaters have been found. This may be because the meat eaters walked in muddy areas where footprints are more likely to leave a good impression and fossilize more frequently than the plant eaters. Toothmarks Toothmarks generally appear in bones. Gizzard Rocks Some dinosaurs swallowed stones to help grind their food modern birds do this also. These stones, called gastroliths literally meaning stomach stones, have been found as fossils. What Are Fossils Written for the KidsKnowIt Network by Brandon Guymon. They are usually smooth, polished, and rounded and hard to distinguish from river rocks. Coprolites fossilized feces Coprolites yield information about the dinosaurs diet and habitats. Coprolites up to 4. A huge theropod coprolite was recently found Sasketchewan, Canada. The only meat eater large enough in that area at that time was Tyrannosaurus rex. Burrows and Nests Fossils of dinosaurs burrows and nests can reveal a lot about their behavior. Enchanted LearningOver 3. Web Pages. Sample Pages for Prospective Subscribers, or click below.
