“Ediacaran fossils are represented by Charnia, a sagittate fossil reaching up to 0.6 m in length.”

“The leaves are smooth, linear, and sagittate, terminating in a sharp point.”

“Although M. friedrichstahlii Rchb. f. also has a strap-like tegula, it has a very distinctive viscidium that is remarkable for its sagittate format and rigid texture.”

“In single gene dolichocephaly only the posterior end of the sagittal suture line is prematurely narrowed.”

“Note that notoungulates, too, have sharp rostra, inflated auditory bullae, and sagittal crests.”

“There was an organized thrombus in multiple sections of the superior sagittal sinus, with the thrombus showing an ingrowth of fibroblasts.”
