Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

Before I start, I would like to introduce myself. I am Blakedog. I've always had an interest in Speculative biology, future evolution especially, and I always create new creatures that I think do or will exist. I hope to please you all with my ideas. Without further adieu, I present the Polycene.

The Polycene

Introduction

Species come and go. It's an age old rule and process that has been around for the 3.8 billion years of the existence of life. Animals and plants either adapt or become extinct due to the environmental pressures around. It is survival of the fittest. Six mass extinctions have managed to wipe out 99% of all life on planet Earth, whether it be gamma rays, meteors, volcanic activity, etc. But the sixth mass extinction in particular was an interesting one. It was the first mass extinction to be cause by a complex species called Homo sapiens, also known as Humans. Humans originated in Africa and then spread out to colonize other continents, leaving their mark everywhere they went. Humans have had impacts on the environments around them. They destroyed habitats, threw ecosystems into peril, introduced non-native species into new continents, used fossil fuels which poisoned the atmosphere, bred beyond their carrying capacity, overhunted and overfished. Things were so bad that more than 75% of species went extinct in a few hundred years, which is no time in a geologic time scale. Due to the loss of biodiversity, humans themselves went extinct earlier on in the 6th mass extinction. The earth was inherited by the survivors. No terrestrial animal (with the exception of feral donkeys, camels, goats, pythons, deer, and pigs due to their extreme flexibility) above 100 pounds survived. This was the test of adaptability. For 10 million years the earth was plunged in an on and off cycle of ice age with the longest lasting 2 million years. After that, habitats and life begin to bounce back and diversify, marking the start of the Polycene (Many age), 49 million years after today.

Species: Thalasaurus atlanticus
Weight: 4 tons
Length: 23 feet (male) 21 feet (female)
Habitat: Atlantic ocean
Lifespan: 20-25 years
Ancestor: Mangrove monitor (Varanus indicus)

-Feeds on the young of whale-like seals, large fish, aquatic mink descendants, etc.
- Behaves more like a shark than a reptile when giving birth. Females swim to shallow water, lays their eggs, and swim off, leaving their babies to fend for themselves upon hatching.
- It takes a few weeks rather than months for eggs to hatch. This is an adaptation for the ocean lizard to thrive.
- Being cold blooded means they have to live in warm waters. If caught in cold waters, their temperature drops, their muscles seize up, and they won't be able to move.
- Young Thalasaurus are preyed upon by whale-like seal descendants.
I never get unamused when people speculate a return of giant sea lizards in the future. I really do like your depiction of monitors taking to the oceans. However I do want to point out some things you may find useful for Thalasaurus.

1) Monitors actually have a heart that, while it has three chambers like most reptiles, can at times act as a four chamber heart during systole which gives it a similar cardio and respiratory rate to that of mammals; meaning they can be warm blooded momentarily. It wouldn't be a great stretch for it to fully evolve endothermism. This also means they aren't just restricted to warm waters (though how prepared it is for cold waters can vary).

2) Some snakes and lizards are capable of giving birth since their eggs are soft shelled and can be retained in the body when they hatch. So very much like how marine mammals can give birth underwater, so can marine reptiles like Thalasaurus, especially considering extinct reptiles like Mosasaurs were viviparious.

3) It might also be worth noting that it wouldn't take too long to grow to super sizes. Maybe Thalasaurus faces some stiff competition (and you even mentioned it is preyed on by giant whale-like seals) which prevents it from growing too large but it would only take maybe 10 million years for it to reach a giant size, and it might grow to the 15 metre lengths the giant mosasaurs reached once they found a niche they could exploit and further evolve with. Maybe given time they would prey on the seals!

There's nothing wrong with your creature at all and you can choose to ignore this post, I just thought you might like to know some facts is all :)

Species: Common wingfin (Pteropinna vulgaris)
Weight: 4 lbs
Length: 1.3 feet
Habitat: Atlantic ocean
Ancestor: Red gurnard

-Descended from the red gurnard
-Incredibly fast, swimming at speeds of 50mph
- Wing-like pectoral fins push water downward in a diagonal line, allowing the fish to propel itself forward
- It can launch it self 8 feet in a single push
- When enough momentum is built up, the fish can also soar through the ocean (It only takes 5 pushes to reach this) like a bird in the sky

Species: Spotted Jet shark (Velosqualus maculatus) (Aka Cheetah shark)
Weight: 51 lbs
Length: 5 feet (Female) 3 feet (Male)
Habitat: Atlantic ocean
Ancestor: Shortfin mako shark

-Shortfin mako sharks are already fast, but took speed to the next level, evolving into a new species of shark called the Jet sharks
- Jet sharks hunt wingfins, the fastest non-predatory fishes in the ocean
- The evolved specialized gills behind their pectoral fins in which the gills in front of the pectoral fins suck in water and the gills behind the pectoral fins push out the water, similar to a jet engine sucking in and pushing out air
-This special adaptation makes them the fastest fish in the ocean, capable of reaching speeds of 70 mph, and helps them escape predators
