Background The honey bee, Apis mellifera, is frequently used as a sentinel to monitor environmental pollution. In parallel, general weakening and unprecedented colony losses have been reported in Europe the USA, many factors are suspected play central role these problems, including infection by pathogens, nutritional stress pesticide poisoning. Honey pollen samples collected from eighteen apiaries of western France four different landscape contexts during periods 2008 2009 were analyzed...
Mystacodon selenensis Lambert, Martínez-Cáceres, Bianucci, Di Celma, Salas-Gismondi, Steurbaut, Urbina & Muizon, 2017 is a toothed mysticete that represents the earliest member of suborder in current state knowledge. Its holotype relatively complete skeleton from upper Eocene (early Priabonian, c. 36.4 Ma) Yumaque Member Paracas Formation southern coast Peru. The thorough description this specimen presented here and reveals numerous similarities with contemporaneous basilosaurids including...
Abstract Since its description in 1840, the toothed whale Squalodon was conceptualized as a transitional form between archaeocetes‐like Basilosaurus and modern whales (Odontoceti). The cranial morphology of approximates that odontocetes; however, their dental patterning more closely resembles archaeocetes. Despite representing form, Squalodontidae have been neglected scientific study. poor taxonomy family is primary cause: significant specimens not redescribed, including type species, S ....
The three extant sperm whale species, the giant Physeter macrocephalus and diminutive Kogia are relict members of superfamily Physeteroidea, whose evolutionary history is traced back to late Oligocene. Although well-preserved diagnostic cranial remains relatively scarce, physeteroid fossil record reveals a considerable degree morphological disparity (especially during Miocene), suggesting that whales occupied broader range ecological niches in past. Here, we provide detailed descriptions...
Hundreds of fossil marine vertebrates cropping out at Cerro Colorado (Pisco Basin, Peru) are identified and reported on a 1:6500 scale geological map in joined stratigraphic section. All the fossils from lower strata Pisco Formation, dated this area to late middle or early Miocene. They particularly concentrated (88%) interval 40 75 m above unconformity with underlying Chilcatay Formation. The impressive assemblage includes more than 300 specimens preserved as bone elements belonging mostly...
The sequence stratigraphic framework and a summary of the fossil fauna upper Miocene portion Pisco Formation exposed along western side Ica River (southern Peru) is presented through new geological map encompassing an area about 200 km 2 detailed chronostratigraphic analyses. Extensive field mapping sedimentological study outcrop sections have shown that cyclical sediment unit composed at least three fining-upward, unconformity-bounded depositional sequences, designated P0, P1, P2 from...
Abstract Wild bees are declining, mainly due to the expansion of urban habitats that have led land-use changes. Effects urbanization on wild bee communities still unclear, as shown by contrasting reports their species and functional diversities in habitats. To address this current controversy, we built a large dataset, merging 16 surveys carried out 3 countries Western Europe during past decades, tested whether influences local taxonomic community composition. These encompassed range levels,...
Abstract: Eight skulls of beaked whales (Cetacea, Odontoceti, Ziphiidae), in six cases associated with elements the mandible, were collected from a limited area (about 1.5 km2) and roughly same stratigraphic horizon at Cerro Colorado, 35 km south-south-west city Ica (Peru), where late Middle Miocene basal strata Pisco Formation crop out. They represent highest concentration reported fossil Ziphiidae. These finely preserved Colorado fossils are described assigned to new species Messapicetus...
Although modern beaked whales (Ziphiidae) are known to be highly specialized toothed that predominantly feed at great depths upon benthic and benthopelagic prey, only limited palaeontological data document this major ecological shift. We report on a ziphiid-fish assemblage from the Late Miocene of Peru we interpret as first direct evidence predator-prey relationship between ziphiid epipelagic fish. Preserved in dolomite concretion, skeleton stem Messapicetus gregarius was discovered together...
Cynthiacetus peruvianus Martínez-Cáceres & Muizon, 2011 is a Dorudon-like basilosaurid (Cetacea, Basilosauridae), being one of the largest members family. The holotype this species sub-complete skeleton, which comes from late Eocene (Priabonian) Otuma Formation on southern coast Peru. A thorough description specimen presented here. differs other genus (C. maxwelli) in having fewer accessory cusps distal and mesial edges p3 p4. Its skull shows general pattern skull, relatively monotonous...
One-hundred and ninety-two fossil marine vertebrate specimens, preserved as bone elements cropping out at Cerro Los Quesos (Pisco Basin, Peru), are identified reported on a 1:4,000 scale geological map in the corresponding stratigraphic section. All fossils originate from Pisco Formation, which is dated this area to late Miocene (from 7.55 Ma ≥6.71 Ma, based 40Ar/39Ar analyses of three volcanic ash layers along section). Specimens particularly concentrated near top two main hills, where...
Background Secondary adaptation to aquatic life occurred independently in several amniote lineages, including reptiles during the Mesozoic and mammals Cenozoic. These evolutionary shifts environments imply major morphological modifications, especially of feeding apparatus. (250–65 Myr) marine reptiles, such as ichthyosaurs, plesiosaurs, mosasaurid squamates, crocodiles, turtles, exhibit a wide range adaptations broad overlap their tooth morphospaces with those Cenozoic mammals. However,...
Abstract Exceptionally preserved delicate baleen microstructures have been found in association with the skeleton of a late Miocene balaenopteroid whale dolomite concretion Pisco Formation, Peru. Microanalytical data (scanning electron microscopy, probe microanalysis, X-ray diffraction) on fossil are provided and results discussed terms their taphonomic paleoecological implications. Baleen fossilization modes at this site include molding plates tubules, phosphatization. A rapid formation was...
—The fossil record of odontocetes (toothed cetaceans) is relatively scarce during the Oligocene and early Miocene compared with later in Pliocene; most odontocete families from these epochs are known by a limited number species specimens. Among those, Squalodelphinidae family small- to medium-sized platanistoids single-rooted teeth, which until now has included only four genera based on diagnostic material, Europe, Argentina, North America. Recent field work Pisco-Ica desert, southern coast...
