| Company Involved | Colossal Biosciences, based in Dallas. |
| Species Revived | Dire wolf (Canis dirus), extinct for over 12,500 years. |
| Genetic Materials | DNA extracted from 13,000-year-old tooth and 72,000-year-old skull. |
| Technology Used | CRISPR gene-editing on gray wolf cells to create embryos, implanted in a domestic dog surrogate. |
| Puppies Born | Romulus (Male), Remus (Male), Khaleesi (Female - inspired by "Game of Thrones"). |
| Ecological Concerns | Criticism over recreating ecological functions and ethical implications of de-extinction. |
| Preservation Efforts | Cared for on a 2,000-acre preserve, certified by American Humane Society and USDA registered. |
