Jag har haft ginkgo blad i plånboken i lite över ett år och jag tror det ligger lite sanning i det.
Mer kul fakta om Ginkgo och tidigare ginkgoarter är möjligen att de uppskattades som föda av vissa dinosauriearter och liknande. Fyndet av fossila frön i magområdet hos shenzhouraptor, eller Jeholornis vilket den oxå kallas visar att frön fanns på menyn hos dessa dinosauriefåglar. Även om man nu ännu inte vet vad för träd som fröna tillhör så liknar de mycket fossila ginkgofrön.
"Another significance of the discovery is the fossilized seeds found in the dinoavian stomach. This means that the bird was fed on plant seeds. In the past, there were many fossils of primitive birds reported but few had anything to do with their feeding habits as direct evidence. The well-preserved plant seeds in the body of a Mesozoic dinobird are the first report of this kind in the world. Among the hundreds of avian fossil specimens ever excavated from China, this is the first sample with direct evidence about the bird's feeding content. Although the bird's teeth are found having gone through a long way of degeneration, its upper and lower jaws are robust and well-developed. Scientists believe this resulted from the adaptation to its feeding habit. Other interesting phenomena are the extensive and massive distribution of the seeds and their well-preserved state as most of the seeds still have their smooth and intact surface. What still puzzles scientists is the taxonomic affiliation of the seeds. Palaeo-botanists say they don't know whether they belong to angiosperm or gymnosperm plants. But one thing is certain, they believe, with more complete specimens of Mesozoic plants to be brought to light in the future, the puzzle will certainly demystified. (Zhao Baohua & Guo Haiyan)"
