As of recent years, scientific discoveries of well-preserved soft tissue and feathers trapped in amber have been made with the possible chance of discovering dinosaur DNA, which was previously considered impossible prior to the first moment of such findings.
===Soft tissue samples with a possible chance of preserved DNA===
•In the case of Mary Schweitzer from Montana State University, when she discovered blood vessels of a Tyrannosaurus rex preserved by iron, along with osteocytes and collagen from an 80 million year old Brachylophosaurus canadensis and the samples collected from Shuvuuia and Rahonavis, she began to ultimately reveal her finds to her colleagues, such as paleontologist Jack Horner, and other scientists, although not without facing controversy.
•Creationist Mark Armitage, who was fired by California State University Northridge, discovered well-preserved soft tissues within two horns from the famous dinosaur known as Triceratops.
•In China, scientists have used ultraviolet light scanners and discovered soft tissues within the remains of the feathered dinosaur known as Epidexipteryx, which lived in the Jurassic period about 130 million years ago. Another discovery was made in the studying of embryos from the Early Jurassic dinosaur named Lufengosaurus.
•With the help of well-preserved soft tissue from the herbivorous dinosaur known as Stegoceras, scientists managed to reconstruct the nasal region of the creature to gain a better view of the dinosaur’s breathing.
•According to recent studies, preserved soft tissues of extinct post-Mesozoic animals, such as the wooly mammoth, Smilodon, the thylacine, and the dodo, have been discovered and would become fitting candidates for the artificial environment, allowing them to live alongside the resurrected dinosaurs.
•With the discovery of preserved soft tissue found in 2009 within the Daohugou Bed of China, we can also have the possibility of cloning the pterosaur known as Jeholopterus.
- During research over the complex early evolution of the "breastbone" featured in birds, well preserved soft tissues from specimens of the species Anchiornis and Sapeornis.
• A soft-tissue cranial crest is described for the hadrosaurid Edmontosaurus regalis
- Mosasaur soft tissue discovered with a bilobed tail fin.
