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.

Xenogene; How life bounced back after a mass extinction

Xenogene

Posted Image

There were a variety of creatures that walked this earth. Giant creatures, swimming creatures, even bipedal creatures thrived in many different habitats. Unfortunately all of those animals are gone now. Extinct. Animals such as Wolves, Tigers, Lions, Buffalo, Bears, and even Humans fell victim to forces beyond their control. A seven mile wide meteor struck the coast California, forming the Ventura crater. The impact shot millions of tons of debris into the atmosphere which blocked out the sun, caused tsunamis, and radiated lethal heat worldwide. No land animal larger than 60-70 pounds survived. Aquatic animals held the advantage in that aspect. This is the H-X asteroid, marking the end of the Holocene and writing the beginning of the Xenogene (meaning "strange era"). The Xenogene is a period of rehabilitation and diversity.

Why would all the sharks be descended from goblin sharks?
Not all. Most.
Yes, but why? What's wrong with regular sharks? They've existed unchanged for a very long time.
Hey.

The idea was that this mass extinction was so catastrophic that only a few species of shark and other animals survive.

But why goblin sharks? Sharks have survived all the other mass extinctions unchanged. If goblin sharks had some sort of advantage over typical shark families, they wouldn't be so uncommon and monotypic. And if they became macropredators, they'd probably lose that freaky jaw since it's almost certainly useless for anything besides snagging small, soft bodied prey.

To be fair goblin sharks probably aren't that rare at all, they are just kind of inaccessible.
I REGRET NOTHING

What if denizens of the United States call themselves 'Americans' so as to avoid being called USAliens?

They live in the very depths of the ocean, so yes. They are inaccessible.

In 50 million years

Well, is good to know how when this happen, but, there are still too many plot holes in its history.
Up to this point you have described that organisms that have survived, their future forms, but you has not described how and why, besides the lack of an overview of how the whole planet has evolved and looks at this time.

I'm not trying to be picky about this, I just want some consistency in your project so that others can understand how this future world has developed.

The idea was that this mass extinction was so catastrophic that only a few species of shark and other animals survive.

I think that is already fairly well established, however, is not necessary to have only one species of each type of animal to exemplify. At one point, mass extinctions are capable of annihilating entire groups, but others can easily survive with a considerable number of species.

I would recommend that you not be so specific with survivors, there are some types of animals that really should be named by groups and families, not a species.

Also, goblin sharks are not really appropriate option, they are too specialized, they may be good survivors by the environment where they live, but this type of animal have been in their niche for 125 million years, they survived the K/Pg extinction event and still remain here without major changes.

Several of the current families of sharks have existed since the Cretaceous period so that an asteroid would not be an inconvenient.

Well, actually they are the last of its family, and also its range is too limited for its lifestyle.

I agree with DT-a bull shark or a dogfish would be a better choice.

But other species of shark do survive like the tiger shark, blacktip reef shark, and blue shark.

So why would most sharks be descended from goblin sharks?

You know, maybe would be good if you see this two guides for make a good and accurate project before continuing this, I would not want us to spend whole pages arguing about if that is or isn't right in your project without reaching any conclusions.

That reminds me, I still have to update that thread.
Projects and concepts that I have stewing around
Extended Pleistocene- An alternate future where man died out, and the megafauna would continue to thrive (may or may not include a bit about certain future sapients)
Inverted World- An alternate timeline where an asteroid hit during the Barremian, causing an extinction event before the Maastrichtian. Dinosaurs, pterosaurs, and notosuchians make it to the present, along with a host of other animals.
Badania- Alien planet that has life at a devonian stage of development, except it exists in the present day.
Ido- Alien world where hoppers (derived flightless ballonts) and mouthpart-legged beasts are prevalent.
Leto- Life on a moon orbiting a gas giant with an erratic orbit; experiences extremes of hot and cold.
The Park- ???
Deeper Impact- a world where the K-Pg extinction wipes out crocodilians, mammals, and birds; squamates, choristoderes, and turtles inherit the earth.
World of Equal Opportunity- alternate history where denisovans come across Beringia and interact with native fauna. Much of the Pleistocene fauna survives, and the modern humans that end up crossing into North America do not overhunt the existing animals. 10,000 years later, civilizations exist that are on par with European and Asian societies.
The Ditch- Nothing is what if seems..

Seems like n interesting project, can we see these new dogs or cats? And will we ever sea any smaller animals? Because it seems like everything returned to the size of animals that went extinct, wouldn't they be smaller? That's usually how it works in the case of dinosaurs being the largest land creatures and mammals being smaller.
