The blood vessels soaked in red blood cells remain recognizable after sitting at room temperature for two years.[Paleo-Art: Illustrations Bring Dinosaurs to Life]Searching for soft tissue Dinosaurs' iron-rich blood, combined with a good environment for fossilization, may explain the amazing existence of soft tissue from the Cretaceous (a period that lasted from about 65.5 million to 145.5 million years ago) and even earlier.Then, in 2007, Schweitzer and her colleagues analyzed the chemistry of the proteins.They found the proteins really did come from dinosaur soft tissue.‘Come and try our ionized alkaline water, guaranteed to slow aging!We can even help install the entire dispensing unit in your home so your family can enjoy it too!
The bones of these various specimens are articulated, not scattered, suggesting they were buried quickly.
Categorization skills, for example, are developed in infancy,...
In the 1990s, chemists began to better understand the impact of their activities on safety and sustainability, and took steps to address these issues.
According to new research, iron in the dinosaur's body preserved the tissue before it could decay.
The research, headed by Mary Schweitzer, a molecular paleontologist at North Carolina State University, explains how proteins — and possibly even DNA — can survive millennia.
