Paleobotanists have found fossils of perhaps world's earliest herbaceous angiosperm plant from the mid-Jurassic period (more than 164 million years ago) in north China's Inner Mongolia.
中国古植物学家在内蒙古发现了可能是世界上最早的中侏罗纪时期(1.64亿多年前)草本被子植物化石。
The finding was published on the latest English edition of Acta Geologica Sinica, an academic journal owned by the Geological Society of China.
The plant -- Juraherba bodae -- was found near in the southeast corner of Inner Mongolia by Professor Han Gang of the palaeontological center of Bohai University in Liaoning Province.
Less than four centimeters tall, the fossil has root, stem, leaves and fruit well preserved. "The occurrence of fructifications implies that the plant is already mature," Han said. "The small size of this mature plant indicates that Juraherba is a herbaceous seed plant, most likely an angiosperm. The seeds enclosed in the fructifications further confirm angiospermous affinity3."
It could be the earliest record of herbaceous seed plants as well as of herbaceous angiosperms. "Most Western botanists2 believe that angiosperms originated from the early Cretaceous period (about 125 million years ago), but the discovery of Juraherba bodae moves that date back 40 million years," Han said.
