Tendons<\/a> are elements connecting muscles and bones. In most vertebrates, they are flexible and elastic but in dinosaurs (including birds) some of them ossify<\/a>. The excellent state of preservation of ossified tendons of three dinosaurs allowed discovery of fossilized soft tissues. Structures resembling fibril<\/a> bundles, blood vessels, and bone cells were identified, resembling those present in ossified turkey tendons. The research indicates that dinosaur tendons ossified through metaplasia<\/a>, i.e., mineralization of already differentiated soft tissues.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
