In the future I may write an article on living fossils, but for now, post some living fossils for discussion!
The most interesting living fossil in my opinion is Nautilus pompilius , the Chambered Nautilus.
Fascinating creatures, by studying them we can learn about Cephalopod evolution. For example, instead of the suction cups found on all other living Cephalopod groups, the Nautilus has tiny hooks on their tentacles. Also, their eye structure is very primitive when compared with other living Cephalopods.
A species of shark rarely seen alive because its natural habitat is about 2,000 feet under the sea was captured on film by staff at a Japanese marine park this week. (…) Marine park staff caught the 5 foot (1.6 meter) long creature, which they identified as a female frilled shark, sometimes referred to as a “living fossil” because it is a primitive species that has changed little since prehistoric times. (…) “We believe moving pictures of a live specimen are extremely rare,” said an official at the park. “They live between 1,968 and 3,280 feet (600 and 1,000 meters) under the water, which is deeper than humans can go.” “We think it may have come close to the surface because it was sick, or else it was weakened because it was in shallow waters,” the official said. The shark died a few hours after being caught.
"When I die, I want to die peacefully in my sleep, like Fidel Castro, not screaming in terror, like his victims."
I dunno I kinda like shark... Some of the ugliest fish are the most yummy.
It is hard to tell sometimes with sea animals, but that fishy did not look too happy. I wonder what an animal that usually lives so deep doing up at the surface?
How about this:
Spoiler Alert, click show to read:
It is the worlds smallest deer. Obviously it is very young compared to those old dudes, but as mammals go it is a relic. I was recently in it's natural habitat (in the temperate rain forests of coastal Chile), but unfortunately I didn't see any, as they are extremely rare. Very odd animals, they nest in trees, and bark to communicate. Also their defiance mechanism is to stand still, make their hair stand on end, vibrate, and cry (seriously), so that may be why they are almost extinct. It is a shame too, because if this does not make your heart melt like wax in July, you have no soul.
The Wollemi Pine is one of the world's oldest and rarest plants dating back to the time of the dinosaurs. With less than 100 adult trees known to exist in the wild, the Wollemi Pine is now the focus of extensive research to safeguard its survival.

The sad part is that the foreign bigger dears introduced by the Chileans and Argentinians in the early 20th century are kind of "exterminating" it by eating his food and starving the population.
Behold, the lowly mudskipper. This fish evolved from some form of Goby ~20 MYa, which is pretty recent in Geologic time. He breathes air using wetted gills, and would actually drown if you held him underwater.
Not a living fossil, but an awesome example of Convergent Evolution...I imagine the first Devonian amphibians ~380 MYa pursued a similar lifestyle...
