Archaeopteris is a member of a group of free-sporing woody plants called the progymnosperms that are interpreted as distant ancestors of the gymnosperms. Archaeopteris reproduced by releasing spores rather than by producing seeds, but some of the species, such as Archaeopteris halliana were heterosporous, producing two types of spores.
This list of fossil sites is a worldwide list of localities known well for the presence of fossils. Some entries in this list are notable for a single, unique find, while others are notable for the large number of fossils found there.
Shanidar Cave (Kurdish: ئەشکەوتی شانەدەر, romanized: Eşkewtî Şaneder, [1] [2] Arabic: كَهَف شانِدَر [3]) is an archaeological site on Bradost Mountain, within the Zagros Mountains in the Erbil Governorate of Kurdistan Region in northern Iraq. [4]
The common nightingale, rufous nightingale or simply nightingale (Luscinia megarhynchos), is a small passerine bird which is best known for its powerful and beautiful song. It was formerly classed as a member of the thrush family Turdidae , but is now more generally considered to be an Old World flycatcher , Muscicapidae . [ 2 ]
Other Carboniferous plant fossils in West Virginia include the leaves of seed ferns Alethopteris. Other Pennsylvanian West Virginian seed ferns included Callipteridium, Callipteris, Lescuropteris, and Linopteris. [11] Neuropteris was a contemporary fern-like plant. [10] The true fern Pecopteris also grew in West Virginia during the ...
The fossil history of flowering plants records the development of flowers and other distinctive structures of the angiosperms, now the dominant group of plants on land.The history is controversial as flowering plants appear in great diversity in the Cretaceous, with scanty and debatable records before that, creating a puzzle for evolutionary biologists that Charles Darwin named an "abominable ...
The whale's remains suggest it's a smaller relative of Basilosaurus cetoides, which lived along Alabama's coast 34-40 million years ago.
Also like the Cretaceous, Kentucky preserves plant fossils from this age. [4] Kentucky's Tertiary flora left behind fossil fruits, cones, flower petals and stems in places like Ballard, Graves, and Fulton Counties. The Wickliffe area of Ballard County has been the source of at least 27 new plant species from that time period.
