Worldbuilding, thank you for your time. I came to this site to ask a few questions and get advice, if possible, on a project I'm working on.
I have always been a fan Turok, Dino Crissis, Cage of Eden, and most recently Fosilfuel. So, this project is basically a love letter to the Prehistoric Horror genre.
A year ago, I read a news what said they may have found the degraded remnants of DNA on the bones of a Centrosaurus and a Hypacrosaurus. Aswell about a news about a scientists retrieved a 80-million-year-old dinosaur protein from a fossil. Don’t know if it has been proven or disproven.
But based on that, I'm planning on writing a series of prehistoric horror stories. The setting is based around the concept of cloned dinosaurs from the Madagascar’s Maastrichtian age, the last stage of Late Creastaceous. Through it would be a science fiction story, I still want my history to be grounded that are plausible, to do a soft science-fiction story.
The concept would be about a of natural substance, chemical or plausible natural occurrence what managed to preserve of proteins fragments from fossils of Majungasaurus, and Rapetosaurus what were near each other, possibly a preserved while locked in battle.
A group/organization of geneticist managed to get sufficient amount of preserved genetic material of Majungasaurus, and Rapetosaurus, enough at least for them to use birds and turtles to fill the missing gaps to form complete DNA structures and make a viable clone or at the very least the closest plausible recreation.
To avoid notice, the research is done in an island on the pacific, of 25kmx25km, of a warm, dry (though humid) coastal environment and seasonal rainfalls. Based on the real-world islands of Bonaire and Aruba. Because the prevailing climate of these Dinosaurs environment was semi-arid.
The Majungasaurus was chosen because being one of the last non-avian Dinosaurs what managed to still exist until the the K–Pg extinction. As well one of the better understood theropods.
The dinosaurs are let to inhabit the island, into a stable but isolated ecosystem. And the characters of a ship wreckage, end up trapped in the island.
So, supposing there was a unique substance or natural occurrence what may have helped preserve enough genetic material of the Majungasaurus and others for 66 million years, the questions are:
• What type of substance, chemical or natural occurrence, real or plausible, may help preserve the genetic materials of the Majungasaurus and others of the region for 66 million years, and viable enough to be cloned or closest genetic modified recreation?
Gratefull for any help or advice.
