Other than myself there are many living relics, many have been known for a long time and some are more recent discoveries. Sometimes these the term 'living fossils' is used, first used by Charles Darwin in his The Origin of Species, when discussing the platypus and the South American lungfish he said....

"...we find some of the most anomalous forms now known in the world, as the Ornithorhynchus (platypus) and Lepidosiren(lungfish), which, like fossils, connect to a certain extent orders now widely separated in the natural scale. These anomalous forms may almost be called living fossils; they have endured to the present day, from having inhabited a confined area, and from having thus been exposed to less severe competition."

Amphibians

The Purple frog (Nasikabatrachus sahyadrensis) is a strange burrowing frog whose only known habitat is in the Western Ghat Mountains of southern India.

Birds
Want to meet a dinosaur, say hello to your canary! Yes, your canary is basically similar to a dinosaur XXXXX Of the bird the Hoatzin (Ophisthocomus hoazin) is perhaps the best example of a living relic, this strange pheasant sizzed bird has claws on its wings.

Fish
The Coelacanth (Latimeria menadoensis and Latimeria chalumnae) is one of the most famous 'living relics', a fish thought extinct for 65 million years turns up in a fishermans net in 1931. Our own Queensland lungfish (Neoceratodus fosteri) belongs to the very ancient group Sarcopterygii, the fleshy-finned fishes from over 400 million years ago. Fossils of fish identical to N. forsteri have been dated at over 100 million years which makes this species one of the oldest living vertebrate species.

Mammals
The Marsupials could all be considered living relics. Surviving on the Australian Arc these creatures died out over the rest of the planet, with the single other exception of the South American Opussum. Even more primitive in form are the Monotremes , these egg laying mammals are represented today by the Platypus and echidnas.  The placental mammals have a few true 'relics'. The Laotian Rock Rat (Laonastes aenigmamus) belongs to a family which had only been known from fossils, the Diatomyidae. The last Diatomyidae fossils are from the Miocene, leaving an 11 million year gap in the fossil record. The Mountain Beaver (Aplodontia rufa) which is actually is unrelated to beavers, is considered a 'living fossil' due to the presence of a host of primitive features.

Some consider the recently discovered cypriot mouse (Mus cypriacus) a living fossil, as it is the only endemic rodent still alive on the Mediterranean islands that managed to survive the arrival of man, with the exception of two species of shrew.

Reptiles
A number of reptiles could be considered as they have continued These

Our earliest fish-like ancestors, evolved with a third hole in their skulls and an eye that connected directly to the brain called the pineal eye. It appears that this adaptation became converted over time to a small organ associated with the control of hormone production — the pineal body or gland.

tadpoles, other amphibians, and some of the lizards, among them the Tuatara, a living relic lizard of the Sphenodont group, a third centrally located eye has remained although the function is not fully understood. It is sensitive to changes in light and dark, but it does not form images, having only a rudimentary retina and lens.

Sharks
Sharks in a good example of how a good design just keeps going, more or less for 350 million years! You could consider them all 'living fossils' as there has been so little change in the basic design. Nonetheless a few deserve special mention. The Frill Shark is a good example how the sea is able to hide living relics! The Megamouth shark is an example of a 'found' cryptid, and it also generated a hoax.

surviving today in the swamps of the Orinoco basin of South America. It is a bird as strange and bizarre as its name, hoatzin, and has succeeded in foxing zoologists for years as to the origins of its odd characteristics. Unable to decide whether it is truly primitive or just an evolutionary throwback, scientists have shelved the problem and placed the hoatzin, Opisthocomus hoazin, in a family or even an order all by itself.
Many features distinguish the hoatzin from other birds, not least of which is its voice which sounds more like a heavy smoker's wheezing than a bird call. About the size of a rather slender, upright pheasant, the hoatzin has an untidy crest of feathers, blood-red eyes encircled by bright blue skin, a long neck and long tail feathers. But perhaps the most interesting characteristic is the presence of claws on the wings and these, although useless to the heavy adult bird, are employed by the youngster to clamber among the branches near the nest- just as Archaeopteryx must have done so many millions of years ago.
The main function of the wing claws, it seems, is to assist the young hoatzin in times of crisis. The nest is normally built on branches overhanging water and is thus exposed to the eyes of marauding hawks. It is a rudely constructed platform of short twigs of roughly pencil thickness. If danger threatens, the parents usually abandon the nest for the safety of dense bushes nearby. The chick, left to its own devices, either uses the wing claws to help it clamber through the branches to some inaccessible spot, or dives into the water and emerges farther downstream to clamber back to 'the nest once the danger has passed.
