  Additionally, an isolated neurocranium from the Late Miocene of the Bahia Inglesa Formation has been attributed to Puffinus, and represents a shearwater larger than P. griseus and P. creatopus. This specimen possibly belongs to the same taxon as the skull found in the Pisco Formation and erroneously attributed to Fulmarus by Cheneval [5]. "A specimen discovered in from the Bahía Inglesa Formation of a right mandible, , belongs to either T. antiquus or T. natans; also found were femurs, , which are not assigned to a species." - same issue as just above. And is this one fine too? User:Dunkleosteus77 |push to talk , 16 January (UTC).

  Highlights This is the most complete review on the dinosaur fossil record of Chile. A critical review is highly relevant as reference for future studies in this field. Including the most complete pelagornithid ever found in the world. New information on the first non-avian species described in the country. Its relevance for understanding animal evolution in the western edge of Gondwana. THE CETACEANS FROM BAHÍA INGLESA FORMATION (ATACAMA, CHILE): TAPHONOMIC APPROACH AND PALEOGEOGRAPHICAL IMPLICATIONS GUTSTEIN, Carolina, Caldera, Chile; SUAREZ, Mario, Museo Paleontologico de Caldera, Caledra, Region de Atacama, Chile The cetacean fossils are abundant and diverse at the bonebed of Bahía Inglesa Formation.

Pygoscelis grandis is extinct species of genus Pygoscelis ("rump-legged") well known as "the brush-tailed penguins". Probably P. grandis is the biggest penquin ever live on the Earth. Bigger than the emperor penguin! Nice fossilization! Bird fossils are very rare always!

Bahía Inglesa Formation bonebed by Aaron A. Walsh Download PDF EPUB FB2

A new monachine phocid pinniped assemblage from the north–central coast of Chile is described. The material was recovered from a marine bonebed of the Bahía Inglesa Formation Cited by: is called the Bahía Inglesa Formation in paleontological literature (e.g.

RojoWalsh and HumeAcosta Hospitaleche and Canto ). The three members of the Bahía Inglesa Formation are (1) the Morro Member, dated to middle-to-late Miocene on the basis of its shark fauna, (2) the Bonebed. Got the bus from Copiapo(bus station is located next to Lider supermarket) to Caldera which took about Caldera you can take a collectivo or taxi to Bahia about 5kms ride and may cost between pesos each way.I was there in the low season so the place /5().

The first diagnostic remains assignable to Spheniscus megaramphus coming from the Bonebed Member of the Bahia Inglesa Formation (Late Mioceno) are presented.

These consist of three isolated. The material was recovered from a marine bonebed of the Bahía Inglesa Formation which, based on macro– and microfossil evidence, is probably Late Miocene–Early Pliocene in age.

The age of the Bahía Inglesa Formation bonebed can be constrained using radiometric data, and microfossil and vertebrate assemblages in the beds above and below the Bahía Inglesa Formation bonebed. Based on the study of the stratigraphy of the microfossils, the overlying Lechero Member is million years (Tsuchi et al.

Three Neogene units have been identified within this basin (Rojo,Marquardt,Godoy et al.,Marquardt et al., ), namely, the Angostura Formation, the Bahía Inglesa Formation, and the Caldera Bahía Inglesa Formation, cropping out between the Copiapó and Caldera Bays (), is a semi-consolidated succession of (bio)clastic and phosphatic rocks characterized.

The type area of the Bahía Inglesa Formation (north–central Chile) is structurally complex as a result of active margin subduction at the Peru–Chile Trench. Inliers of subaerially exposed Mesozoic igneous basement are unconformably overlain by a mid-Miocene to late Pliocene marine siliciclastic sequence, which has become known for its abundance of fossil vertebrates found concentrated in.

Bahía Inglesa Formation is highly fossiliferous, presenting different stratigraphic levels with abundant marine vertebrates (e.g., Walsh and Hume, ; Suárez et al., ;Chávez, Chávez. The age of the Bahía Inglesa Formation bonebed can be constrained using radiometric data, and microfossil and vertebrate assemblages in the beds above and below the Bahía Inglesa Formation bonebed.

Available from British Library Document Supply Centre-DSC:DXN / BLDSC - British Library Document Supply CentreSIGLEGBUnited Kingdo. The aim of this paper is the description of a single tooth collected from the Late Miocene Bahía Inglesa Formation exposed at Las Arenas, 1 km inland from Bahía Inglesa, on the coast of north-central Chile (Fig.

1a).This specimen represents the first fossil sirenian found in Chile and the southernmost eastern Pacific sirenian record, having been collected at latitude 27° S. (c) Depositional environment and sedimentology.

In the road-cut section of the Bahía Inglesa Formation at Cerro Ballena, we measured a stratigraphic section, noted sedimentary structures and observed invertebrate trace fossils (figure 2 a–c).Sediment samples collected from BL1–4 were freshly excavated and covered in optically clear resin (Epo-TekEpoxy Technology, Billerica, MA.

Bahía Inglesa Bahia Inglesa has a small artisan fair, beachside restaurants and kayak rentals, in summer it gets a bit saturated so we recommend booking well in advance, in the low season it is very romantic and quiet, in the high season there are plenty of parties and reels from the beach, you can also visit the Paleontological Museum with interesting samples of the Atacama coastal formation.

Manganese nodules recovered from two stratigraphic horizons of Tortonian–Messinian (late Miocene) age in the Bahía Inglesa Formation of north-central Chile were studied using XRD, SEM and geochemical analysis.

The dominant mineral in the nodules is todorokite, which suggests a diagenetic, marine environment. The type area of the Bahía Inglesa Formation (north–central Chile) is structurally complex as a result of active margin subduction at the Peru–Chile Trench.
