These fossils can show us more about the family tree of modern crocodilians and how they evolved.

Sedimentary rocks interpret dinosaur habitats through encased environmental structures of the past. Through sedimentary rocks, paleoecologists’ can examine the arranged formation of sedimentary structures to specify what type of environment the dinosaurs’ lived in. An example of a specific sedimentary rock structure can be seen through formed weathering and ripple marks by how wind and sand formed distinct patterns in the past layered sediment. These arrangements provide interpretations on the structure of the sediment and the habitat of encased fossils, through modern day comparisons

Condition: Upon examination of the remains, there were soil stains apparent on the upper ribs, as well as the skull and upper vertebrae. There is evidence of insect and scavenger activity, apparent from the damage to the right femora, and right pubic.

In a statement, Dr. Gilbert Price, a vertebrate palaeoecologist expresses his disbelief at having uncovered the find, “Our jaws dropped when we found a tiny fossil from a giant lizard during a two meter deep excavation of one of the Capricorn Caves, near Rockhampton. The bone, which scientists have classified as an “osteoderm,” 0.4-inch (1-centimeter)

Every so often a discovery is made that attempts to shake up pre-conceived notions of how the dinosaurs actually lived or how they came to be. On June 22, 2000, in Oregon, scientists announced the discovery of the oldest known animal to have feathers. Though no records indicate how the age of the animal was determined, the

Six new species of dinosaurs have been found after researchers from the University of Alberta analyzed theropod teeth from eight regions in Spain.

Therefore I believe a dinosaur could have been in my backyard because of sedimentary rocks being the only rock to be able to contain fossils and these rocks being found in the sand dunes at Hallett Cove Beach, the fossils found of an ancient sea creature having a relation to dinosaurs and opal being a popular rock to mine and this being a way of preserving underwater fossils in their original state.

In 2005, Palaeontologist Mary Schweitzer and her team made the discovery of finding original soft tissue, including blood vessels, in a Tyrannosaurus Rex fossil in Montana. Many of Schweitzer's fellow scientists insisted that she had been mistaken because of previous theories of how fossils were preserved. The fossil was buried in a permeable sandstone, where groundwater could get in. Since organic material is quickly broken down in water, the soft tissue should have decayed quickly under the conditions. When an animal dies, the soft tissues (skin) decays and disappears over time, while hard tissues (bone) may gradually obtain minerals from the environment and become fossils. Evolutionists scrambled to propose a reason on how the soft tissue could have been completely preserved in pristine condition (Fields, H. 2006) (Morris, D. 2005). The extensive study of bones from New Zealand’s extinct giant Moa bird calculated that the lifespan of DNA should be measured in thousands, not millions of years. Therefore the unfossilised dinosaur bone is

While excavating a meteorite crater in northeastern Iowa's Winneshiek Shale, paleontologists discovered the fossil of an enormous and bizarre ancient scorpion species that lived in the ocean. It is now believed to be Planet Earth's earliest large predator. The findings were published in the journal BMC Evolutionary Biology on August 31st, 2015.

The reading passage states that paleontologists intentionally split a fossilized bone of a 70 million-year-old dinosaur, called T-Rex, and discovered several substances that might be the original tissue of the dinosaur, such as blood vessels, red blood cells, and collagen. However, the lecturer casts doubt on it and provides conclusive evidence to support his statement.

First, the broad cheek bones and broad skull are consistent of those of a robust australopithecine (McFarland). Whereas gracile australopithecines and Homo erectus species have a skinnier face and not as prominent check bones. Also, robust also have a small brain size resulting in less cranial capacity than the others. The second factor I considered was the sagittal crest that appeared to be on top of fossil #9’s cranium. For robust australopithecines, the sagittal crest is a bony ridge on top of the skull located more towards the back. (Dorey) The other crania at the station were missing this key feature which made them easy to eliminate. The third element I was looking for during my observation was the prognathism of the face, meaning the face was projecting forward (McFarland). This helped me eliminate the fossils I was unsure about. For example, fossil #8 had robust facial features like a prominent brow ridge but lacked the prognathic face robust australopithecines

Joseph Tyrell made the first significant dinosaur discovery as the leader of his first expedition to find coal. He found Alberta’s “. . . first good dinosaur specimen – the skull of an Albertosaurus on June 9th, 1884.” (Tanke and Currie, 1198). The skull was very damaged by the extraction because Tyrell and his team were not paleontologists and had no experience in digging or preserving fossils. They did not even have the correct tools.

I can conclude that the dinosaur had a bipedal posture, and as a result it walked on its back legs only. It also have three toe facing forward and pretty sharp claws. I can also conclude that the front legs were not equipped to support them. Maybe, the front legs was used for gripping and tearing their prey instead.

It can be a fun and stimulating information when you are scanning for dinosaur fossils, for instance, bones and eggs. Territory is the huge criteria to make sense of fossils and if you are at the unequivocal place and know not the bone then there is an open entryway for you to get reward by a bone of a soonest creature.
