many of today’s oceans and seas. These “oceans” were small and shallow giving way to an excellent, warm, tropical climate.” “Surface waters in the low latitudes were about 20 °C (68 °F), while deep waters were about 17 °C (63 °F).” Some of the plant fossils

a) What is the definition of a fossil? A fossil is well known as the remaning parts of past life preserved in rock, soil or amber whose name has originated from the latin word ‘fossus’ meaning ‘dug up’. b) Identify three types of fossils and describe them, giving examples i) Trace fossils are known as preserved evidence that have been left behind from an animals action.Trace fossils capture the movement of ancient animals. For example, when the animals leave their footprints behind, it creates an

In 1983, the fossil remains of Georgiacetus vogtlensis was unearthed at a nuclear power plant facility in Burke County, Georgia. The discovery of G. vogtlensis was phenomenal because it directly linked protocetid ancestors to modern day whales. G. vogtlensis lived 40.5 million years ago in the southeastern region of the united states during the Bartonian age of the Eocene epoch. Cranial measurements recorded a skull 12in wide, 24in deep and 30in long, suggesting a total body length of 10 to 20ft

in a new environment known as the region, Poobah. There were human fossils remains found in this environment and we needed to figure out how long they might have been there underneath all of the soil layers based off of the evidence and knowledge we had from the soil layers above the fossils remains that were found. Inductive and deductive reasoning helped us gather the information and get a conclusion of how old the human fossils remains roughly were, found by the data we were able to collect on

Placoderms are an extinct class of armored fishes.Placoderms were the first vertebrates to have jaws. They are paraphyletic, and comprise several distinct out groups or sister taxa to all living jawed vertebrates. Placoderms evolved from agnathan (jawless) fishes in the Silurian period, about 425 million years ago. They first appeared in the Early Silurian and diversified dramatically during the Devonian and Carboniferous periods and became extinct in Permian.

Title: Recognize the procedure to search and purchase genuine dinosaur fossils 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. If you are genuinely organized and well characteristic on the most ideal approach to enhance your probabilities

1. a) What are the major global events that occurred in the Proterozoic? (3) Three global events occurred during the Proterozoic: The oxygen revolution: During the Proterozoic, biotic system were being established, which gave rise to biomass of the prokaryotic organisms like the “benthic and planktonic photosynthesizing organisms” Due to the vast developing diversity of environment, organisms could well adapt to these various environments, which increased the input of oxygen on Earth. Hence

jaw), right and left upper ribs, partial right ilium, both ulnae (forearm), right forearm bone, finger bones, claws, right femur (thigh), both tibiae (shin bones), right fibula (calf bone), right ankle bone, foot bones, foot claws. Almost all the fossils were discovered at the bottom of a Billabong near the town of Winton, Queensland. The site was known as Billabong Bonebed, where the greatest amount of dinosaur bones of the Australovenator and diamantinasaurus ever in Australia. In 1981 near Eagles

How old is the Siberian Husky breed? When you look at the physical differences between different dog breeds, you could be forgiven for thinking that some of them are so different that they can only be very distantly related; for instance, the little Chihuahua shares very few physical traits with say, the Newfoundland dog. However, all dog breeds worldwide actually share 99% of their genes, and just 1% of the genes within any breed will be different to any other. Since the advent of DNA analysis
