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...
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...
This paper describes a ∼200 m-thick section of the Pisco Formation exposed at Cerro Colorado, an important fossiliferous site in Ica desert. In order to properly place fauna its correct relative position, this study establishes stratigraphic framework within which different fossil-bearing intervals can be compared and may prove invaluable future high-resolution studies on faunal change. Most deposits Colorado consist gently dipping fine-grained sandstones, diatomaceous siltstones diatomites...
Strata of Chilcatay and Pisco formations exposed in the Ica Desert (East Basin, southern Peru) preserve one most complete rich records Miocene marine vertebrates world. Despite its exceptional importance, chronostratigraphy these fossil-bearing deposits has been only sporadically studied literature until recently. This work presents a detailed reconstruction chronostratigraphic framework, achieved by mapping measuring seven sections (totaling height almost 1000 m) along western side River....
The Miocene Pisco Formation, broadly exposed in the Ica Desert of southern Peru, is among most outstanding Cenozoic marine Fossil-Lagerstätten worldwide. It renowned for its exceptional preservation and abundance vertebrate fossils, including a rich assemblage whales dolphins (Cetacea). Here, we integrate taphonomic data on 890 gathered through 16 different localities. Our observations range from taxonomic distribution, articulation, completeness, disposition orientation skeletons, to...
This paper is the first integrated account of sedimentology, stratigraphy, and vertebrate paleontology for marine strata Chilcatay Formation exposed at Ullujaya, Pisco basin (southern Peru). An allostratigraphic framework investigated was established using geological mapping (1:4000 scale) conventional sedimentary facies analysis resulted in recognition two unconformity-bounded allomembers (designated Ct1 Ct2 ascending order). The chronostratigraphic well constrained by integration...
The Mio-Pliocene Pisco Formation, Peru, is a world renowned Konservat-Lagerstätte.Beside its potential in preserving important information on the history of Pacific Ocean during Miocene, Fm. provides palaeontologists with unique opportunity to study detail evolution marine vertebrate fauna Neogene.Because diatomites are one main lithologies Fm., previous authors have hypothesised exceptionally high sedimentation rates related deposition diatom frustules as cause leading formation...
The upper Neogene Pisco Formation of Peru is known worldwide as one the most significant Cenozoic marine vertebrate Konservatt-Lagerstätten, even featuring cetacean specimens that retain remains soft tissues or stomach contents. Previous works showed biomediated precipitation dolomite concretions around large-sized decaying carcasses was relevant processes responsible for exceptional fossil preservation. In turn, little about modes fossilization well-preserved small-sized vertebrates, which...
Abstract One hundred and forty‐four published successions of shallow‐water carbonates, deposited between the Palaeocene Miocene, from Levant to Himalayas, have been re‐analysed using a standardised approach investigate distribution carbonate facies carbonate‐producing organisms. Large benthic foraminifera were found be volumetrically most important group producers during whole period, with peak in abundance Eocene. Colonial corals are relatively abundant their peaks Oligocene has minimum Red...
The enormous concentration of marine vertebrates documented within the Pisco Formation is unique for Peru and South America places this unit among prime fossil Lagerstätten Miocene to Pliocene mammals worldwide. In order provide a robust stratigraphic framework fossil-bearing locality Cerro Los Quesos, study presents 1:10,000 scale geological map covering an area about 21 km2, detailed measured section spanning 290 m strata, refined chronostratigraphy studied succession well constrained by...
The South Asian river dolphin ( Platanista gangetica ) is the only extant survivor of large clade Platanistoidea, having a well-diversified fossil record from Late Oligocene to Middle Miocene. Based on partial skeleton collected Chilcatay Formation (Chilcatay Fm; southern coast Peru), we report here new squalodelphinid genus and species, Macrosqualodelphis ukupachai . A volcanic ash layer, sampled near fossil, yielded 40 Ar/ 39 Ar age 18.78 ± 0.08 Ma (Burdigalian, Early Miocene)....
Field mapping and sedimentological study of outcrop sections exposed along the Ica River valley permitted establishment a regional allostratigraphic framework for upper Miocene portion Pisco Formation. The stratigraphy studied interval is illustrated using new 1:20,000-scale geological map which reveals that this formation cyclical sedimentary succession composed three fining-upward allomembers. bounding surfaces defining each allomember are transgressively modified subaerial unconformities....
The northward-flowing Humboldt Current hosts perpetually high levels of productivity along the western coast South America. Here, we aim to elucidate deep-time history this globally important ecosystem based on a detailed palaeoecological analysis exceptionally preserved middle–upper Miocene vertebrate assemblages Pisco Formation East Basin, southern Peru. We summarise observations hundreds fossil whales, dolphins, seals, seabirds, turtles, crocodiles, sharks, rays, and bony fishes...
The Cenozoic succession of the East Pisco Basin preserves sedimentary record several episodes deformation forearc crust along Peruvian margin. 1:50,000 scale geological map presented here encompasses an area about 1,000 km2 lying astride Ica River, and contributes to our understanding timing mode basin filling deformation. Our novel two-fold megasequence framework provides a sound basis for establishing first-order tectono-stratigraphic setting mid-Eocene–upper Miocene exposed in study area....
Abstract Acorn barnacles are sessile crustaceans common in shallow-water settings, both modern oceans and the Miocene geological record. Barnacle-rich facies occur from polar to equatorial latitudes, generally associated with shallow-water, high-energy, hard substrates. The aim of this work is investigate type by analysing, palaeontological, sedimentological petrographical points view, early examples Northern Italy, Southern France South-western Peru. Our results then compared existing...
ABSTRACT Based on mapping of laterally traceable stratigraphic discontinuities, we propose a high-resolution allostratigraphic scheme for one the world's foremost fossil marine vertebrate Lagerstätten: lower Miocene strata Chilcatay Formation exposed along Ica River near Zamaca, southern Peru. Measured sections combined with 1:10,000 scale 24 km2 area provide an overview stratal architecture, as well general facies framework and interpretation various depositional settings. As whole,...
