Cyanobacteria have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact! It may surprise you then to know that the cyanobacteria are still around; they are one of the largest and most important groups of bacteria on earth.\n\nMany Proterozoic oil deposits are attributed to the activity of cyanobacteria.The cyanobacteria have also been tremendously important in shaping the course of evolution and ecological change throughout earth's history. The oxygen atmosphere that we depend on was generated by numerous cyanobacteria during the Archaean and Proterozoic Eras. Before that time, the atmosphere had a very different chemistry, unsuitable for life as we know it today.\n\nThe other great contribution of the cyanobacteria is the origin of plants. The chloroplast with which plants make food for themselves is actually a cyanobacterium living within the plant's cells. Sometime in the late Proterozoic, or in the early Cambrian, cyanobacteria began to take up residence within certain eukaryote cells, making food for the eukaryote host in return for a home. This event is known as endosymbiosis, and is also the origin of the eukaryotic mitochondrion.\n\nSo, to put it in a nutshell, they are the oldest, they created the oxygen atmosphere and they allowed plants to feed themselves.  Amazing for such a small little thing.

Primates are remarkably recent animals.  Most species of living things had become extinct long before the first monkeys and their prosimian ancestors evolved.  While the Earth is about 4.55 billion years old and the first life dates to at least 3.5 billion years ago, the first primates did not appear until around 60 million years ago.  That was after the dinosaurs had become extinct.\n  \n\n \n65,000,000 years ago\n \n\n \npresent \nTransitional primate-like creatures were evolving by the end of the Mesozoic Era (ca. 65 million years ago).   At that time, the world was very different from today.  The continents were in other locations and they had somewhat different shapes.  North America was still connected to Europe but not to South America.  India was not yet part of Asia but heading towards it.  Australia was close to Antarctica.  Most land masses had warm tropical or subtropical climates.\n \n\n \n  \n Small Insectivore from the\n end of the Mesozoic Era \nThe flora and fauna  at the end of the Mesozoic Era  would have seemed alien since most of the plants and animals that are familiar to us had not yet evolved.  Large reptiles were beginning to be replaced by mammals as the dominant large land animals.  Among the mammals, there were a few archaic egg-layers (monotremes) like the ancestors of the platypus and echidna.  There were larger numbers of pouched opossum-like mammals (marsupials).  The few placental mammals that existed at that time mainly consisted of the Insectivore  ancestors of primates.  The large grass-eating placental mammals, such as cattle and wildebeest,  were absent as were the vast grasslands that would later develop.  Rodents and small-seed eating birds were also absent.  The great proliferation of flowering plants had not taken place yet, however, forests of broad-leafed trees were developing over much of the earth.\n\n\nProto-primates\n\nThe first primate-like mammals, or proto-primates , were roughly similar to squirrels and tree shrews in size and appearance.  The existing, very fragmentary fossil evidence (mostly from North Africa) suggests that they were adapted to an arboreal  way of life in warm, moist climates.  They probably were equipped with relatively good eyesight as well as hands and feet with pads and claws for climbing.  These proto-primates will remain rather shadowy creatures for us until more fossil data becomes available.\n\nEarly primate-like mammals do not seem to have played an important role in the general transformation of terrestrial animal life immediately following the massive global extinctions of plants and animals that occurred approximately 65,000,000 years ago.  The most dramatic changes were brought about by the emergence of large grazing and browsing mammals with tough hoofs, grinding teeth, and digestive tracts specialized for the processing of grass, leaves, and other fibrous plant materials.  The evolution of these herbivorous  mammals provided the opportunity for the evolution of the carnivorous  mammals specialized to eat them.  These new hunters and scavengers included the dogs, cats, and bears.  Adaptive radiation was resulting in the evolution of new species to fill expanding ecological niches, or food getting opportunities.  Most of these new animals were placental mammals.  With the exception of bats, none of them reached Australia and New Guinea.  This explains why they did not exist there until people brought them in recent times.  South America had also drifted away from Africa and was not connected to North America after 80,000,000 years ago.  However, around 20,000,000 years ago, South America reconnected with North America and placental mammals streamed in for the first time, resulting in the extinction of most of the existing marsupial fauna there.\n\n\nEarly Prosimians\n\nThe first primates may have evolved during the last part of the Paleocene Epoch .  These were members of the genus Altiatlasius .  Their bones have been found in 60,000,000 year

bristlecone pines have around 4,600 tree-rings and are still the world's oldest living organisms. (Bristlecone pines are native to the Rocky Mountains of the United States.)\n\nBUT, maybe its not since.. \nOn a wild Tasmanian mountain there is a magnificent, recently discovered stand of Huon pine trees that has been called the world's 'oldest known living organism'. \nIt is hard to see how a tree could be older than the time since the biblical Flood, so if its published age of ,more than 10,500 years old' were correct, then this would present a serious challenge to Old Testament chronology. In fact, some media reports claim the tree 'could be 30,000 or 40,000 years old'.

well you say animals...so I think the first animals would have been similar to that of fish due to the large area occupied by water. And they would have no bone, probably use their skin to breathe.\nIf you're talking about bacteria...then yes, it would have to anaerobe because it is believed that the first form of life was some sort of bacteria and at that time there was no oxygen present.\nAnd I think plants too were first found in water.

The modern chicken is generally believed to be a descendant of "Archaeopteryx", the oldest known bird. This 150 million year old resident of the Jurassic period laid eggs, and at some point of time, evolved into an animal that was one generation away from being a proper chicken. This creature would have produced the egg out of which the first chicken emerged...the EGG came first.

The oldest known artificial shelter is believed to be 500,000 years old, built by homo erectus. Clearly, our understanding of human history allows for a 40,000 year old structure.

Birds are the direct descendents of dinosaurs.  Many scientists will say they *are* dinosaurs.  As such, they are alive, so dinosaurs are alive.\n\nWhile it remains possible that some dinosaurs proper have survived, it is extremely unlikely at this point.  There is no physical evidence for it.\n\nYour second question is difficult to answer.  Are there prehistoric creatures that have survived?  Sure!  Pretty much every species on earth today (even humans!) is older than history, that makes it prehistoric!  Defining prehistoric any other way would essentially make prehistoric mean "not surviving today", so the answer would be no.\n\nWhat you mean, of course, is creatures to have survived from truly ancient times, such as from the Mesozoic (age of dinosaurs) or older, but again, it's difficult to answer.  There probably aren't any actual species that old, but it's difficult to tell if something in the fossil record is actually the same species as something alive today.  Consider, lions and tigers look and act very different alive and are certainly two different species, but it is very difficult to tell their skeletons apart.\n\nA lot of so-called "living fossils" really aren't.  For instance, we have no fossils of the Coelacanth.  It's closest relatives in the fossil record are in another family (as different as cats and dogs).  Cockroaches are often said to have been unchanged for millions of years, but it's not the case as the fossil record records them evolving continuously.  The first fossil cockroaches had three pairs of wings!\n\nBut some things have survived nearly unchanged for millions of years.  Six-gill and Port Jackson sharks are very much like they were in the age of dinosaurs.  The Tuatara is surprisingly like it's Mesozoic relatives.\n\nBut the king of living fossils is the Lingula brachiopod.  It looks like a clam and lives by filter feeding, but don't let it's calm appearance fool you.  These little guys are survivors.  They've been living in Earth's oceans almost unchanged for 550 million years!  That's almost as long as we have animal fossils at all!  Dinosaurs are hardly teenagers by comparison!\n\nAddenda:  The Komodo Dragon is NOT believed to be a dinosaur, at least not by scientists.  It is just a large monitor lizard.  Dinosaurs are not lizards, being classed among the Archosaurs with the crocodiles, pterosaurs and birds.
