rex. This dinosaur looked like a smaller, less muscular version of Tyrannosaurus. As an early member of the tyrannosaur family, Albertosaurus was the final design for the large meat-eating dinosaurs. It only had two fingers on its hands, which were at the end of short arms. It had long legs and it a wide skull with lots of power in its bite.
For instance the frog and toad both have bulging eyes; however, the frogs’ eyes are slightly bigger than the toads. As you read on you will learn the differences and similarities between the frog and toad. There are 2000 known species of the frog compared to the 300 kinds of toads. A frog is a small, slim, four legged amphibian with smooth skin and long powerful hind legs with webbed feet. The biggest frog is the Giant frog, sometimes called “Goliath Frog,” in West Africa.
List the general characteristics of vertebrates. The general characteristics of vertebrates are two unique features of vertebrates: a skull and a backbone. The skull forms a hard case for the brain. The backbone is composed of a series of skeletal segments called vertebrae (singular, vertebra), which enclose the nerve cord. 4.
Ranging in size from 30 g (1.1 oz) to 9 kg (20 lb), lemurs share many common, basal primate traits, such as divergent digits on their hands and feet and nails instead of claws (in most species). However, their brain-to-body size ratio is smaller than that of anthropoid primates, and among many other traits they share with other strepsirrhine primates, they have a "wet nose" (rhinarium). Lemurs are generally the
Strepsirhines are evolutionarily the furthest from AMH within the primates, and as shown by their names are mainly distinguished by the nose (rhine) – strepsirhines have a curly nose whereas the haplorrhini have a simple nose – i.e. the strepsirhines have the median groove running up to the rhinarium between either nostril, a feature which does not occur in happlorhines. Another major feature is the tapedum lucidum – i.e. the reflective layer in the eye that allows for improved night vision. Hence, the majority are nocturnal, they are relatively asocial and fairly small in size compared to the haplorrhini.
Lucy is about 3.18 million years old, and is called Denkenesh in Amharic, the language of the local people. I was very intrigued by the findings of the Australopithecines. The idea that Lucy was closely related to the human species was amazing. Lucy was bipedal and her brain was smaller than that of modern humans. Lucy resembled an ape and was able to make tools to find food and weapons.
About eighty-six percent of their diet is leaves, shoots and stems, seven percent is roots, three percent is flowers, two percent is fruit and the remaining two percent consists of ants, snails and grubs (Bonnett, 1986). The gorillas’ incredible strength allows them to easily break apart vegetation. They are rather fastidious when it comes to selecting what they consume and may only eat the leaves, pith, stalk or roots of the plant. They use their agile lips and hand dexterity to manipulate vegetation for the particular portion they would wish to deplete. The Mountain Gorillas do not over exploit for rapid replenishment to occur.
They weigh around 2000-2,800 pounds. Adult males and females are usually dark on the head, especially the top of the head and upper and lower jaws. Unlike most other whales, narwhals have no dorsal fin, instead they have a low bumpy ridge that begins midpoint of the back and continues to the fluke, or tailfins. The “horn” that gives the narwhals the name “Sea Unicorn”, is actually a tooth that can reach up to nine feet long and can weigh up to twenty pounds. Both males and females are born with two teeth pointing forward in the upper jaw, but the left tooth of the male grows long and spirals counter clockwise toward the tip.
Since there position on the trophic level the Diprotodon had many predators including the Marsupial Lion and a Megalania. Giant Short-faced Kangaroo - (Procoptodon goliah) Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Diprotodontia Family: Macropodidae Genus: Procoptodon The Giant Short-faced Kangaroo was the world’s largest kangaroo. It stood 3m tall and weighed approximately 200kg. Fossils found at the Naracoorte caves establish that the genus died out approximately 50,000 years ago. The kangaroo is supposed to have unusual feet somewhat like a horse.
Until the last few years, humans were separated into their own family within this super family because it was believed that we are considerably different from the apes. Nevertheless, recent genetic studies and discoveries from the fossil confirmations have made it clear that a number of of the apes are extra similar to humans than formerly believed. Subsequently, the living hominoids are now commonly classified into only two families with humans grouped with the great apes in the second family. The first is Hylobatidae, which is gibbons. And the second is Hominidae, which is humans, orangtans, gorillas, chimpanzees, and bonobos.
