Reijenga & Close (2025) study the fossil record of Phanerozoic marine animals, and argue that purported evidence of a relationship between the duration of studied clades and their rates of origination and extinction can be explained by incomplete fossil sampling. [44] Maletz et al. (2025) revise Paleozoic fossils with similarities to feathers ...
Doughty et al. (2025) use a mechanistic model to study the relationship between seed size of flowering plants, their light environment and the size of animals in their environment, and predict a rapid increase of seed size during the Paleocene that eventually plateaued or declined, likely as a result of the appearance of large herbivores that opened the understory, reducing the competitive ...
Dooley et al. (2025) reevaluate the affinities of mastodon fossil material from Oregon and Washington (United States), Alberta and Hidalgo and Jalisco (), extending known geographical range of Mammut pacificus, and providing probable evidence of presence of both M. pacificus and M. americanum in close geographical proximity.
Today, in his home in Reno, Nevada, Case has a collection of more than 2,000 fossils -- mostly teeth from a variety of species, about 10% of which he believes are from various dinosaurs.
Scientists discovered a 520-million-year-old fossilized larva with brains and guts intact, offering unprecedented insights into early arthropod evolution.
Three dinosaur fossils from the Jurassic period will go under the hammer at a London auction on Thursday, with price estimates of millions of dollars. Christie's is offering the skeletons of an ...
Fossils may be found either associated with a geological formation or at a single geographic site. Geological formations consist of rock that was deposited during a specific period of time. They usually extend for large areas, and sometimes there are different important sites in which the same formation is exposed.
The structures are considered to be one of the oldest ecosystems on Earth, according to NASA, representing the earliest fossil evidence for life on our planet from at least 3½ billion years ago.
