Examination of The Winton Dinosaur Project Findings in the Queensland, Australia Winton Dinosaur project show that the sauropod named "Elliot" may have died with his mate by his side (Salleh 2003). Anna Salleh from ABC Science Online discusses the new fossil evidence found by Dr. Steve Salisbury from the University of Queensland, who is one of the leading researchers on the Winton Project (2003). Dr. Alex Cook and assistants Scott Hocknull and Dr. Steve Salisbury lead the Winton Project. Elliot is one of the largest dinosaurs found to date in Australia, dating to about 98-95 million years ago (Beirne 2001). According to researchers, Queensland, Australia was covered by a vast inland sea during the time of the dinosaurs 98-95 million

Some of our important human characteristics, such as a spinal cord encased in a bony vertebral column, and the concentration of nerve cells in a brain, are part of our vertebrate heritage, established in a common ancestor over 600 million years ago. From our mammalian heritage, established over 70 million years ago (though some of these common traits may go back over 200 million years), humans developed internal mechanisms for maintaining a constant body temperature (warm-bloodedness), hair, and a generalized dental pattern that allows a more varied diet than is found among other vertebrates. The reproductive pattern of mammals is an especially distinguishing trait: They usually give birth to live offspring (versus laying eggs), nurse their young with milk produced in the female’s mammary glands, and have complex social mechanisms for the care of the very young. All living organisms must cope with the problem of how to survive and reproduce within their environments. Adaptation refers to the relationship between an organism and its environment: When we say that a population is adapted to its environment, we mean it has achieved and maintained a relationship to that environment in which it can survive and reproduce
In the late 1990s, a species was introduced into the waters of the Atlantic Ocean, becoming an invasive species: the lionfish. The lionfish, a venomous marine fish found mostly in the Indo-Pacific waters, is distinguished by its red, white, and black stripes, striking pectoral fins and its venomous spiky fin rays. The lionfish ranges in its size from 6.2 to 42.2 cm, with an average adult measuring the size of 38cm and weighing 480 grams, living 5-15 years. This venomous species is well known for its beautiful venomous spines and unique tentacles. Younger lionfish have a unique tentacle above their eye sockets, which differs in appearance between species, but studies show that this tentacle has evolved over time in each species serving to attract new prey.
For the most part primates are classified quadrupedal. Primates travel in methods of brachiation, vertical clinging and leaping, knuckle walking, and bipedalism for modern man. Through natural selection and evolution primates developed an increase of hair density changes in body configuration and have shifted to having a gradual upright stance. Grade I-Lemurs The first grade of primates came in the Paleocene epoch, about 65 million years ago. It is the most primitive, and it includes true lemurs, galagos and lorises.

Preliminary Biology – Research Task 1) Assess the impact of three particular technological advances on the understanding of the platypus. Technology is a major tool that has been used over the last century to understand organisms better, specifically the platypus. The Platypus was first encountered by Europeans in 1798, where they thought somebody had sewn a duck’s beak onto a beaver-like animal. Since then, our understanding of the Platypus has increased and the following three technological advances have shown how and why it has increased. a) Electron Microscopy: The electron microscope is a type of microscope that uses a beam of electrons to create an image of the specimen.

Geo 202 Ichthyosaurs Ichthyosaurs, the Greek word for fish lizard, were a marine animal far from what its name implies. They played the role of what whales, seals, and dolphins play in today’s marine ecosystem. From fossil records, geologists can tell a lot about the life ichthyosaurs lived throughout the years it roamed the seas, including their body structure, how they reproduced, what they ate, where they lived, and much more including their extinction. Based on fossil evidence, the ichthyosaur first appeared around 245 million years ago. Although earlier forms had a sleek, lizard like body, most had a body structure that most resembled modern day mammals (Perkins).
