User blog:Jurassic Park Treasury/Australian Extinct Animal Park Idea Thing

On Park Pedia, back in 2010, I made a blog post about my plan to create a dinosaur park on Cocos Island. That obviously didn't pan out. While recreating non-avian dinosaurs from ancient DNA will never happen, improvements in the field of ancient DNA and genome engineering (especially with the discovery of CRISPR) have given the possibility of recreating other extinct species. And of course, there is Jack Horner's chickenosaurus research and other evo-devo research that could be used to create birds with dinosaur traits (I will refer to these as dinosaur facsimiles.

I have a renewed idea for a park of extinct animals. I am not saying that this is feasible, or that it will definitely happen. This is merely an idea based on current science and emerging research.

This more realistic park would be located in Australia. It would feature dinosaur facsimiles and resurrected extinct animals. I have looked to the academic literature and the Sixth Extinction website for extinct species with suitable museum specimens or subfossils from which DNA can be found. From my research, I have chosen several extinct species which I think could yield enough DNA to assemble a reasonably complete genome which could then be compared with the genome of an extant relative. The genome of the close relative would then be edited in a cell culture. For mammals and amphibians, a nucleus from this cell culture would be put into a surrogate mother or egg. For birds and reptiles, a chimera would need to be created with some engineered primordial germ cells. The chimeras would then hatch, grow up, mate, and lay eggs that produce the new version of the extinct species (this method has an extra advantage as it doesn't require the surrogate be closely related).

But I digress. Here are the species that I think would be suitable for the park, as well as info on specimens:


 * Round Island burrowing boa: The holotype specimen is in the Muséum National d'Histoire Naturelle in Paris. Three specimens are found in the London Natural History Museum, and another at the Museum für Naturkunde in Berlin.
 * Rodrigues giant saddle-backed tortoise: A stuffed specimen exists in the Muséum National d'Histoire Naturelle in Paris, as well as subfossil bones in other parts of Europe. Mitochondrial DNA has been extracted from some of these remains.
 * Gallotia goliath: Mitochondrial DNA has been extracted from mummified specimens of this lizard. It is unknown if nuclear DNA could also be extracted.
 * Kawekaweau: Only known from one specimen, which could yield DNA. Even if there isn't enough DNA to assemble a genome, mitochondrial DNA could elucidate the true origins of the specimen.
 * Cuban macaw: At least fifteen skins of this extinct parrot exist in the US and Europe.
 * Huia: 119 skins of this bird exist in New Zealand museums alone.
 * Carolina parakeet: 700 skins exist worldwide.
 * Paradise parrot: I do not know how many specimens of this parrot exist, but they do exist.
 * Heath hen: A de-extinction project for this species already exists: http://longnow.org/revive/projects/heath-hen-project/

And here are the hypothetical dinosaur facsimiles that I think could be produced for this park:


 * Chickenosaurus: A modified chicken with a tail, hands and teeth.
 * Urvogel: A modified perching bird (probably zebra finch) with a tail, hands, teeth, carnivorous diet and black feathers.
 * Ratitosaurus: A modified emu with a tail, hands and teeth.
 * Dynamosaurus: A modified chickenosaurus, designed to be much larger, with two clawed fingers instead of three, and more tyrannosaur-like skull features and cervical ribs.

The extinct reptiles would be housed in a large reptile house, while the extinct birds and urvogel would be housed in an aviary. The dinosaur facsimiles would be found in enclosures. I may add more species to the list, depends on what I think might be possible in my lifetime (the average New Zealand lifespan in 1999 was 77 years, so I'm assuming that I'll die in 2076).

Expect this blog post to be edited in the future.
