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.

Should we clone Megalania

Sop since scientists are planning to clone a woolly mammoth in the future this brings me a question Should we clone a megalania? They gone extinct quite recently and could we find the genomes for it since it lived in a much warmer climate and what would we do with them once there brought back to life?

Future project ideas:
Tale of the horned beasts - A alternate evolution project where ceratosaurus never went extinct and instead evovled to better fit the new challenges they shall face ahead of them.

Umber - A alternate universe project where portals have been opening up to a moon named "umber" other then a few species of freshwater and saltwater fish, as well as invertebrates. Pangolins,Iguanas,Noasauriade, and Cuttlefish are the most prominet group of animals.

I don't think so because we already have the Komodo Dragon and that would literally drive the species into extinction.
Megalania is like one of those species you were glad are now extinct.

OK, let's just start off with from what I can tell that animal tissue in colder climates have a better chance of preserving DNA then hotter ones.

The most we could do with cloned megalanias are let them run wild, to say nothing of introducing a large predator go an ecosystem which has adapted without it, or start some megalania-skin fashion industry.

Actually, there hasn't been much adapting since the Pleistocene in Australia. Other than a couple of species dwarfing, little has changed. All native animals there are used to having large monitors as predators, both from the past with Megalania and in the modern times with the Perentie. It would probably be the Megalania that would be in trouble, its adapted to slow-moving large prey. Maybe it could eat feral camels or something?

Nuclear DNA is very unlikely to be preserved in megalania remains (unlike mitochondrial DNA, and even that is questionable). The closest we could get is reintroducing the Komodo dragon.

When it comes to resurrecting recently extinct megareptiles, Mekosuchus and Meiolania are more likely candidates, as they went extinct very recently and scientists have been getting better at sequencing DNA from tropical climates.

Not sure where you got this idea from, but no, there is no reason at all to think Komodo dragons would somehow drive Megalanias into extinction.

Nobody has ever cloned an animal with shelled egg.

For all it's advanced promise, cloning is currently a brute-force technology. We scrap out the nucleus of a eggs, and stick in the nucleus of a different cell. It's been two decades since it's been possible and still don't understand everything about how it works.

We can only do that with amphibian eggs and and mammalian ones. And even then, cloning is very hit and miss. Most clones don't survive, generally the survival rate hovers between less than one percent to ten percent. Dolly the sheep was the 277th sheep they tried to clone, for example.

We've got a long road to this being possible.

I think he meant megalania driving komodo dragons extinct. Either way, there's no reason megalania would end up on Komodo or the other Indonesian islands.

There's another way to generate genetically modified birds and possibly reptiles with heritable traits that doesn't involve cloning.

I think the answer is the same as with megalania, not for the moment and near future, as far as it has been explained, the cloning of animals is still quite limited, besides there is not enough genetic material to do it.

What would it take to make cloning a bird or reptile possible, I wonder?

In the end, the best advice I could give you would be to do your project in a way that feels natural to you, rather than trying to imitate some geek with a laptop in Colorado.

There'd be even less DNA for Quinkana than megalania, likely none at all.

Mekosuchus is a possibility for resurrection, but cloning wouldn't do it. Just germ cell transmission as is usual for birds (not sure if it can be extended to hard-shelled egg layers in general).
