However, only the lowermost 0.5 to 1.5 metres (2 to 5 feet) of Eospermatopteris trunks were preserved, and the plant's branches and foliage remained unknown for more than 130 years.
Most traffic is in the lowermost 35-mile (56-km) portion of the river.
Lochkovian Stage, lowermost of the three standard worldwide divisions of Early Devonian rocks and time.
Traditionally, marine rocks stratigraphically above the Keuper Marl in Germany and the New Red Sandstone in Britain have been regarded as either uppermost Triassic or lowermost Jurassic.
The correlation of the Rhaetian of northwestern Europe with that of the Alps has been questioned, however, and it has been suggested that the former may actually be lowermost Jurassic in age.
Llandovery Series, lowermost of four main divisions in the Silurian System, representing those rocks deposited worldwide during the Llandovery Epoch (443.4 million to 433.4 million years ago).
Spikelets characteristic of Rhynchospora and its allies and Cladium and its allies are derived by a reduction in the number of flowers per spikelet and a sterilization of lowermost or uppermost flowers, as well as by the conversion of some bisexual flowers to staminate only; in Rhynchospora, for example, male flowers are above the perfect flowers, and in Cladium male flowers are below.
The Huronian System is well known in the Great Lakes region and has been divided into three major series of rocks: the lowermost, the Bruce Series, is followed in turn by the Cobalt and Animikie series.
However, recent studies suggest that the lowermost Werfen may contain Permian fossils.
Frasnian Stage, lowermost of the two standard worldwide divisions of Late Devonian rocks and time.
One edge of the leaf overlaps the other, resulting in a slight dwarfing of the edge that is lowermost.
