Dinosaurs did not exist 30 million years ago. They all died out 65 million years ago at the end of the Cretaceous time period. You are probably referring to preserved soft tissue. It is very rare for 65 million year old fossils to have intact soft tissue fossils, because in the process of making fossils, soft tissue is the first tissue to degrade and disappear. "Viable" to me means still living. Nothing is alive as a fossil. If you would like to point out to me "30 million year old" zombies, do so, and bring your source. Do not bring politics into this. However I may predict a creation argument coming, I don't want to dispute that, just disputing your evidence.
Schweitzer et al reported extraction of pliable organic material that was vessel like. Not confirned if they were actual blood vessels. Moreover, the tissue was fossilized/embedded in a rock matrix that still needed to be dissolved. Finally she was able to identify protein epitopes in the non avian dino sample with an antibody that was formulated to recognize ostrich peptides

Very useful! Easy to follow along and teaches a lot
29:51/30:01 Confirming a hypothesis? Surely we want to reject a null hypothesis?
Excellent lecture. Thank you, Prof. Patel.
A must read: "Endless Forms Most Beautiful: The New Science of Evo Devo" by Sean B. Carrol (Prof. Nipam Patel is cited too)

The absolute state of California: “there was an earthquake and an embryo rolled over. This is a disaster!”
Earthquakes are the reason bacterial conjugation wasn't discovered in CA.
haha!
Can anyone explain the viable blood vessels found in the "30 million" year old dinosaur bones?
I do not get the purpose of this comment.
Santa. In the beginning there was void and emptiness. And Santa said, let it snow, let it snow, let it snow! Ho ho ho!
