I know for a fact that Coelacanths are often referred to as living fossils, because the two living species closely resemble their prehistoric counterparts that evolved 409 million years ago. But recent studies have shown that coelacanths are more diverse than previously thought with many different forms appearing in the fossil record, and genetic analysis has shown that The West Indian Coelacanth and Indonesian coelacanth are very distinct from their prehistoric counterparts, so I say no, they're not living fossils, but I want to hear some other's opinions on the subject.

15 years ago today I came into existence.
Here’s a big shiny book on prehistoric life I got.
A look inside.
The rest of the stuff I got was just money and Stranger Things merchandise, so now I’ll post random dinosaurs and stuff like I did last year.
Coelocanths are parrot fish.
Imperobator, the dromaeosaur that wasn’t a dromaeosaur.

The Tyrannodon hasn't stumbled across any old creature. This is Megastropheus, the terror of the coasts!
The Megastropheus snaps at the Tyrannodon, and the mammal runs away. The Megastropheus flashes its fangs and plods down the beach.
Megastropheus is a type of unique reptile called a Tanystropheid. Earlier in the Triassic era, they were bizarre lizards with ridiculously long necks and small legs, hunting fish in shallow water. Now, they have grown larger, their legs lengthening, and their jaws turning into the weapon of an apex predator.
Thanks to @KaijuNerd for Megastropheus depiction!
The Tyrannodon keeps running until the Megastropheus vanishes from view. Out over the waves, a few Pax circle overhead, occasionally diving to skim the waves.
Pax are highly specialized pterosaurs. With longer, narrower wings, they can travel long distances and swim over the ocean waves, grabbing any fish near the surface. The paxids have given up mobility for size and durability.
The Tyrannodon turns away and moves on. It finds a large dead sarcopterygii fish on the beach and sniffs at it. Opening its jaws, it eats at the fish's rotting flesh.
Luck at last! A sea creature washed on the beach by the raging storm.
The Tyrannodon gulps down the last of the lobe-finned fish and turns. It plods further down the beach eyes always alert.
Under other circumstances, the Tyrannodon would be the top predator of the earth. But in this world, the giant crocodilians protect their title as undisputed rulers. And so these mammals, for the time being, must live under their shadows.
We move out over the ocean, with Pax swooping around.
The pterosaurs however, live under no animal's shadow. They rule the skies, unchallenged. The first vertebrates ever to fly.
A Pax swoops over the waves and dips its beak in.
They have it made, swooping over seas and lands teeming with food. But the way they catch this food is rather strange.
The Pax's beak hits a fish and its snaps shut.
It's primitive wings can't afford to get wet, so it grabs surface fish another way. A beak dipped in the ocean, snapping onto anything it hits.
The sun begins to dip behind the swirling ocean. The Pax soar into the sky above a land of new life.
Just 30 million years before, the earth had suffocated in a blanket of heat, killing nearly all life on earth. But from the ashes of the fire, life arises anew, stronger than ever. The first giant flyers rule the skies.
Below on the shore, Megastropheus creeps along, looking left and right for prey.
And new predators have taken the greatest bites of the animal kingdom. But this world is still subject from change.
A Fasolasuchus pads along beside the desert oasis, sniffing the air. Nearby a Desmatosuchid lies motionless, dried out and dead from starvation and thirst.
What is a desert now, will soon be flooded with water. The earth is changing, breaking apart. And when it does, the cracks will fill in with water.
A dark fin cuts through the surface of a new ocean.
And creatures will fill that water...
