Overview of the events of 2025 in paleontology
| |||
|---|---|---|---|
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 2025.

Other animal research
- A study on fossil material of the tommotiid Lapworthella fasciculata from the Cambrian strata in Australia is published by Bicknell et al. (2025), who report evidence of increase of thickness of sclerites of L. fasciculata and increase of the frequency of perforated sclerites through time, and interpret these findings as the oldest evidence of evolutionary arms race between predator and prey reported to date.

A member of Pseudogaudryininae. The type species is F. sirhanensis. |
History of life in general
- Zong et al. (2025) report the discovery of a new assemblage of well-preserved fossils (the Huangshi Fauna) in the Silurian (Rhuddanian) strata in south China, including fossils of sponges, cephalopods, arthropods and carbon film fossils of uncertain identity.
Other research
- Evidence of slow accumulation of Australian sediments preserving Archean mudrocks with high organic content is presented by Lotem et al. (2025), who interpret their findings as consistent with lower primary productivity in Archean than in present times.
- Cowen et al. (2025) study the geochemistry of dental tissue of Devonian fish fossils from Svalbard (Norway) and Cretaceous lungfish and plesiosaur fossils from Australia, and interpret their findings as indicative of preservation of the primary chemical composition of the bioapatite in the studied fossils.
Paleoclimate
- Evidence of low atmospheric CO2 levels throughout the main phase of the late Paleozoic icehouse, and of rapid increase in atmospheric CO2 between 296 and 291 million years ago, is presented by Jurikova et al. (2025).
- Evidence indicating that abrupt climate changes during the Last Glacial Period increased pyrogenic methane emissions and global wildfire extent is presented by Riddell-Young et al. (2025).
