The Dongoconodon specimen preserved multiple tooth generations across incisors, canines, premolars and molars, described as the first mammal known to show repeated replacement across all four broad tooth categories.OBSERVATIONALSupported
Dongoconodon platycauda had expanded feet resembling webbed platypus feet and a flattened tapering tail interpreted as adaptations for swimming and steering.OBSERVATIONALSupported
Dongoconodon platycauda, an approximately 125-million-year-old Early Cretaceous mammal from China, is the earliest confirmed swimming mammal discovered to date.HISTORICALSupported
Recalibrated radiocarbon dates reported by the study place the Mizyn figurines among Europe’s earliest anthropomorphic images after the Last Glacial Maximum and suggest an independent Palaeolithic stylistic phenomenon.HISTORICALSupported
The study reports that Palaeolithic artists used Schreger and Owen’s natural lines in mammoth ivory to inform geometric compositions engraved on many Mizyn figurines.INTERPRETIVESupported
A 2026 study used digital and microscopic analysis to examine 18 mammoth-ivory figurines from Mizyn, Ukraine.OBSERVATIONALSupported
The 2011 tsunami and its backwash brought marine Japan Sea stickleback and freshwater threespine stickleback into the same newly formed freshwater pond in Iwate, resulting in interspecific hybridization.HISTORICALSupported
The study reported that Iron Age reoccupation at Bakr Awa integrated divergent preceding Bronze Age ancestries rather than replacing them.COMPARATIVESupported
The study reported substantial Bronze Age genetic heterogeneity at Bakr Awa, including Anatolian, Levantine, and Caucasus/Yamnaya-related ancestry influences.OBSERVATIONALSupported
The study analyzed DNA from 17 Bronze- and Iron-Age individuals at Bakr Awa in northeastern Iraq.QUANTITATIVESupported
The study described Tel Shiqmona's industrial compound as the largest known Iron Age purple-dye factory in the Mediterranean.COMPARATIVESupported
The Tel Shiqmona study reported that purple-dye production was probably integrated into the compound's seasonal activity cycle during complementary time windows.INTERPRETIVESupported
The 8th-century BCE industrial compound at Tel Shiqmona was used for different activities in different seasons, including olive pressing in late autumn, livestock sheltering in winter, and textile production in spring.HISTORICALSupported
The study described the Antiochia ad Cragum site as the largest agricultural-processing installation found so far at that ancient city.COMPARATIVESupported
The agricultural-processing phase of the Small Bath at Antiochia ad Cragum dates broadly to the fourth through seventh centuries CE.HISTORICALSupported
The Small Bath at Antiochia ad Cragum was later converted into a large facility for wine and olive-oil production.HISTORICALSupported
The reported associations between ancient Maya features and modern forest structure were strongest at spatial scales of approximately 100 to 300 metres, and their wider geographic extent remains untested.QUANTITATIVESupported
In the studied old-growth forest of northern Belize, ancient Maya wetland fields, settlements, and upland walls were each associated with distinct modern forest-structure metrics.COMPARATIVESupported
In the Brazilian Cerrado, open-air village populations consumed substantial maize, whereas contemporaneous rock-shelter populations had more diverse diets and little evidence of intensive maize use.COMPARATIVESupported
Some precolonial Brazilian Cerrado societies sustained large villages through maize grown within diversified agricultural systems rather than intensive monoculture.HISTORICALSupported
Across the studied Bronze Age Greek communities, non-local individuals represented roughly 5–10% of analyzed individuals, were most likely among young adults under 30, and were not identified among the children studied.COMPARATIVESupported
Strontium-isotope comparisons identified 17 non-local individuals among 199 Bronze Age individuals from six archaeological sites in central and southern Greece, with childhood origins potentially elsewhere in Greece.QUANTITATIVESupported
The study characterized Bianfu Cave as a Denisovan locality with the most abundant Denisovan remains outside Denisova Cave in Siberia.OBSERVATIONALSupported
The study identified three hominin fossils from approximately 167–134 thousand years ago and reported proteomic confirmation of those bones and two excavated teeth as Denisovan.OBSERVATIONALSupported
The study screened more than 60,000 Bianfu Cave bone fragments, selecting 76 for zooarchaeology by mass spectrometry and 17 for proteomic sequencing.QUANTITATIVESupported
In the study’s fossil synthesis, Western and Central European tree-genus richness declined 75% from its Miocene peak to the Holocene.QUANTITATIVESupported
The study compiled 711 fossil occurrences representing tree genera from Western and Central Europe across the Cenozoic.QUANTITATIVESupported
The study identified Bianfu Cave as a Denisovan locality with the most abundant Denisovan remains outside Denisova Cave in Siberia at the time of the report.OBSERVATIONALSupported
In the study’s Bayesian protein phylogenies, each of the five Bianfu Cave samples formed a monophyletic group with Denisova 3 with posterior probability of 100%.QUANTITATIVESupported
Proteomic analysis identified five Denisovan specimens from Bianfu Cave: three newly identified hominin bone fragments and two previously excavated hominin teeth.OBSERVATIONALSupported
The Canjuers locality preserves the youngest Jurassic turtle fauna currently known from Europe.COMPARATIVESupported
Two Canjuers fossil specimens represent the new thalassochelydian species Caesaria templaria, characterized by a medium-sized skull, short snout, and a well-developed pygal bone lacking a pygal notch.OBSERVATIONALSupported
Yujingia preserved pinnate arms with filter-feeding grooves, and the study inferred that ancestral ambulacrarians evolved from semi-sessile organisms with complex suspension-feeding adaptations.OBSERVATIONALSupported
The 518-million-year-old fossil Yujingia glutenotunica is phylogenetically placed within a grade of tentaculate fossils immediately basal to the last common ancestor of modern ambulacrarians.COMPARATIVESupported
A nearly complete Early Cretaceous eutriconodontan skeleton from China shows multiple tooth generations at some loci and anatomical adaptations consistent with semiaquatic locomotion, including webbed-like hands and feet and a flattened tail.OBSERVATIONALSupported
Chemical and microfossil analyses of liquid and sediment from a Warring States Qin bronze vessel identified evidence used to determine the ingredients and brewing processes of an ancient alcoholic beverage.HISTORICALSupported
The analyzed Sântana de Mureș-Chernyakhov individuals showed evidence consistent with poor overall health and strenuous physical exertion, with modest access to terrestrial animal protein and millet uniformly dominant over other cereals.OBSERVATIONALSupported
Radiocarbon modeling of 26 Sântana de Mureș-Chernyakhov individuals in a Carpathian cemetery suggests the cemetery was established a few years after the Roman Empire’s retreat, used for only a few decades, and shows no identified founding generation or subsequent large-scale mobility.HISTORICALSupported
In a 3,587-site dataset from Neolithic China, settlement intensity was increasingly concentrated along terrain-accessible corridors from 5000 to 2500 BCE, but this association weakened from 2500 to 2000 BCE as concentration shifted toward intermediate-accessibility settings.COMPARATIVESupported
The reported analysis found a moderate overall correlation between Roman and modern roads across the former Roman Empire, with substantial variation by location.COMPARATIVELeans supported
The reported network analysis found that Rome was not the dominant hub of the Roman Empire’s land-transport network and that Byzantium was more central to empire-wide land mobility.HISTORICALLeans supported
