I read some articles and it would appear they found a T-Rex skeleton long ago and decided to cut into the bone at some point and found bone marrow that was too fresh for their science.
Controversial T. Rex Soft Tissue Find Finally Explained
Interesting enough is the massive weight of the colossal T-Rex beast:
"The most famous of the upright, largely meat-eating dinosaurs called theropods, T. rex would have weighed between 5,000 and 7,000 kilograms (11,000 to 15,500 pounds) with skin and flesh on its huge bones. That's about as much as the largest African elephant." The Problem of Size | AMNH
How are dinosaur fossils preserved and not decay with time?
"The most common process of fossilization happens when an animal is buried by sediment, such as sand or silt, shortly after it dies. Its bones are protected from rotting by layers of sediment. As its body decomposes all the fleshy parts wear away and only the hard parts, like bones, teeth, and horns, are left behind." Dinosaur Bones | American Museum of Natural History
Is that enough weight to fracture a normal bone when the beast is standing on "two" legs? And what of this fossilization that preserves the dinosaur bones, is it fossilization or actual strength of the original structure that had to lift and support 15,500 pounds of muscle. And then is it even 15,500 pounds? What type of muscle did they use in the estimate of the T-Rex weight? Or did it have a more powerful muscle that what we see on earth that would lift and support 15,500 pounds with two bipedal legs. Some muscle actually tears and causes injury with too much exertion or weight.
