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. [46] Maletz et al. (2025) revise Paleozoic fossils with similarities to feathers ...
Fossil material of a giant titanosaur sauropod, distinct from Andesaurus and probably exceeding Patagotitan in size, is described from the Cenomanian Candeleros Formation by Otero et al. (2021). [241] Revision of known fossil material of Pellegrinisaurus powelli and a study on the skeletal anatomy, bone histology and phylogenetic relationships ...
Fossils from before the mass extinction have only been found around the Equator, but after the event fossils can be found all over the world. [13] Suggested explanations for this include: Archosaurs made more rapid progress towards erect limbs than synapsids, and this gave them greater stamina by avoiding Carrier's constraint .
Digitally reconstructed craniums depict fossilized remains found at Xujiayao (left) and Xuchang. The large, low and wide shape is distinct from the skulls of other known hominin species.
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 ...
A study published Wednesday Jan. 16, 2019, found the biggest rise in Siberia, where frozen soil temperatures rose by 0.9 degrees Celsius (1.62 Fahrenheit) between 2007 and 2016. (AP Photo/Arthur Max)
Đaković, Mrdak & Gawlick (2025) describe three assemblages of Anisian ammonoids from the Komarani and Bulog formations (), including fossils of Ptychites rugifer, Megaphyllites obolus, Parakellnerites rothpletzi, Apleuroceras decrescens, Proteusites labiatus, Tropigastrites lahontanus, Proarcestes pannonicus, Proarcestes subtridentinus and Aristoptychites sp. extending known geographical ...
