Scientists have made a remarkable discovery: traces of actual dinosaur blood preserved in a 115-million-year-old fossil bone from Brazil. This marks the first time researchers have successfully identified blood remnants from these ancient creatures, opening an extraordinary window into dinosaur biology.

The preservation of biological material over such an immense timespan is exceptionally rare, making this finding a significant breakthrough for paleontology. By studying these traces, scientists can learn more about the physiology and evolution of dinosaurs in ways previously thought impossible. Read the full story →
