Nonetheless, these Darwinist researchers have been the target of derision and even anger from secular scientists, many of whom have been in denialthe excitement that dinosaur soft tissue generated among young earth creationists, the response from evolutionary quarters has ranged from simply ignoring and overlooking this, the greatest discovery in the history of paleontology (as by the Smithosonian's dinosaur expert Brian Switek and Phys.org), to the dismissal of this research (as by the UK's Prof.

Dinosaur and Dinosaur-Layer Creatures: The dinosaurs and other Mesozoic creatures that have yielded their biological material are hadrosaur, titanosaur, ornithomimosaur [ostrich-like dinosaurs], mosasaur, [bird-like] .As you view the exciting scientific discoveries below in this chronological catalog, please feel free to listen to Real Science Radio co-hosts Fred Williams and Bob Enyart observe their annual tradition of presenting dinosaur soft tissue and other amazing discoveries including short-lived left-handed amino acids, DNA, and Carbon 14, all in bones and other specimens from dinosaur-layer Mesozoic and even deeper strata. (See 60 similar discoveries.) Here, RSR presents the scientific journals reporting, the kinds of biological material found so far, and the dinosaurs yielding up these exciting discoveries: Scientific Journals: , and others below in our chronological catalog, "the web's most complete list of dinosaur soft tissue discoveries," as published in many leading journals, according to a co-author of one of those papers.Biological Material Found: As of 2017, in fossils from dinosaur-layer and deeper strata, researchers have discovered flexible and transparent blood vessels, red blood cells, many various proteins including beta-keratin, the microtubule building block tubulin, collagen, the cytoskeleton components actin, tropomyosin, and the related motor protein myosin, and hemoglobin, bone maintenance osteocyte cells, DNA-related histone proteins, and powerful evidence for DNA including positive results from multiple double-helix tests.Here, we test the hypothesis that this exceptional morphological preservation extends to the molecular level...

We employed antibodies raised against avian feathers, which comprise almost entirely of beta-keratin, to demonstrate that fossil tissues respond with the same specificity, though less intensity, as those from living birds. Our data, obtained using electron microscopy and in situ immunofluorescence, support the preservation of original proteinaceous claw material in this approximately 75 million- year-old oviraptorid dinosaur, [RSR Note: While not all published dinosaur soft tissue researchers are old-earth evolutionists, not surprisingly, the majority are.

Famed paleontologist Jack Horner of Montana State University worked the excavation site.

In a 2011 development, ten leading universities and institutes including Harvard, the University of Manchester, and the University of Pennsylvania published in PLo S One, a peer-reviewed journal, that they had verified that presumed dinosaur material is indeed original biological tissue from a dinosaur!

For example in their conclusion they write about their specimens as, "dinosaur vessels", that their research provides "robust support to the identification of these...
