From Jurassic Germs to Gymnosperms: A Speculative Strategy for Reconstructing Dinosaur Genomes

The longstanding dream of resurrecting dinosaurs faces formidable obstacles. DNA decays rapidly, making direct recovery impossible. Even if successful in their aims, and modern “synthetic” methods achieve a complete and functioning non-avian genome, they cannot recreate specific dinosaur species because at least some of the crucial genetic information is completely absent from living relatives. Alternatively, it is suggested here that microbial vectors once mediated horizontal gene transfer (HGT) between dinosaurs and the ancestors of extant species. While HGT appears rare, the ecological continuity between dinosaurs, microbes, and coexisting plants offers a faint but plausible route for fragments of dinosaur DNA to survived in extant species. Building on advances in paleogenomics, synthetic biology, and comparative genomics, we outline a multi-step strategy to search for, validate, and functionally test dinosaurian “genetic shrapnel” preserved in the “dark genome” of candidate organisms – particularly that of gymnosperms. If such material could be recovered, it might provide missing pieces needed to reconstruct extinct dinosaur species. Even if the goal of dinosaur de-extinction remains forever beyond reach, pursuing this line of research could yield transformative insights in evolutionary biology, synthetic biology, and conservation science — and offer a compelling narrative to engage the public.
