Some of soft tissue finds in fossils….
– Two Dinosaur Soft Tissue Predictions Confirmed! Real Science Radio hosts Bob Enyart and Fred Williams had predicted on air and in writing at rsr.org/predictions that:
– Dinosaur soft tissue will be found not only in rare circumstances, but rather easily, i.e., when looked for. CONFIRMED in 2015! The journal Nature Communications reported original tissue in six of eight dinosaur bones investigated, leading to the conclusion that “preservation is more common than previously thought.” And:
– Original dinosaur and other biological tissue will be found largely independent of the claimed age of the fossil. RECONFIRMED in June 2016! The journal Nature Communications reported original biological material in Gunflint chert allegedly from 1.88 billion years ago in the Proterozoic “Eon” (i.e., layer). First CONFIRMED in 2014, The Journal of Paleontology reported original soft tissue in Precambrian “beard worms” that are allegedly 530 million years old! (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: Nature, Science, PNAS, PLoS One, Proceedings of the Royal Society, Bone, Acta Histochemica, the Journal of Vertebrate Paleontology, Proteome Research, 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 2016, in fossils from dinosaur-layer and deeper strata, researchers have discovered flexible and transparent blood vessels, red blood cells, many various proteins including the microtubule building block tubulin, collagen, the cytoskeleton components actin, tropomyosin, and the related motor protein myosin, and hemoglobin, bone maintenance osteocyte cells, pigment and evidence of melanosomes, DNA-related histone proteins, and powerful evidence for DNA including positive results from multiple double-helix tests.
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] Anchiornis huxleyi, triceratops, Lufengosaurs, T. rex, and Archaeopteryx.
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.
