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.
Archaeamphora longicervia is a fossil plant species, the only member of the hypothetical genus Archaeamphora. Fossil material assigned to this taxon originates from the Yixian Formation of northeastern China , dated to the Early Cretaceous (around 143 to 101 million years ago ).
A Late Pliocene fossil from Rębielice Królewskie , of Piacenzian age (around 3 Ma), could be an ancestral bluethroat. A supposed Sylvia warbler fossil from the late Gelasian of Bad Deutsch-Altenburg ( Austria ), about 2 Ma old, may be of a Luscinia instead; due to its recent age it probably belongs to a living species or its immediate ancestor.
Scientists discovered a 520-million-year-old fossilized larva with brains and guts intact, offering unprecedented insights into early arthropod evolution.
The International Fossil Plant Names Index (acronym IFPNI) is an online database of paleobotany.The site was launched in May 2014 to list the scientific names of fossil plants, algae, fungi, allied prokaryotic forms (formerly treated as algae and Cyanophyceae in particular), algal-related protists and microfossils published using binomial nomenclature.
The private sale of fossils has attracted criticism from paleontologists, as it presents an obstacle to fossils being publicly accessible to research. [2] Most countries where relatively complete dinosaur specimens are commonly found have laws against the export of fossils. The United States allows the sale of specimens collected on private ...
Javan rhinos are herbivores and eat plants. Their diet includes soft twigs, shoots, young leaves, and fallen fruit. Because they require a lot of calories to support their massive bodies (2,000 to ...
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 ...
