A Diverse Upper Jurassic Dinosaur Ichnofauna from Centralwest Portugal A diverse Upper Jurassic dinosaur ichnofauna from central-west Portugal OCTA´ VIO MATEUS AND JESPER MILA` N Mateus, O. & Mila`n, J. 2010: A diverse Upper Jurassic dinosaur ichnofauna from central-west Portugal. Lethaia, Vol. 43, pp. 245–257 A newly discovered dinosaur track-assemblage from the Upper Jurassic Lourinha˜ Forma- tion (Lusitanian Basin, central-west Portugal), comprises medium- to large-sized sauro- pod tracks with well-preserved impressions of soft tissue anatomy, stegosaur tracks and tracks from medium- to large-sized theropods. The 400-m-thick Lourinha˜ Formation consists of mostly aluvial sediments, deposited during the early rifting of the Atlantic Ocean in the Kimmeridgian and Tithonian. The stratigraphic succession shows several shifts between flood-plain mud and fluvial sands that favour preservation and fossiliza- tion of tracks. The studied track-assemblage is found preserved as natural casts on the underside of a thin bivalve-rich carbonate bed near the Tithonian–Kimmeridgian boundary. The diversity of the tracks from the new track assemblage is compared with similar faunas from the Upper Jurassic of Asturias, Spain and the Middle Jurassic York- shire Coast of England. The Portuguese record of Upper Jurassic dinosaur body fossils show close similarity to the track fauna from the Lourinha˜ Formation. h Dinosaur tracks, Lusitanian Basin, Portugal, skin impressions, Upper Jurassic.

The probable sources of these sediments were generated in Carboniferous to Early Paleogene times (,315 to 60 Ma). The total depths of individual James Ross Basin formations are discussed. The AFT data were modelled, and the thermal history model was reconstructed for samples from Seymour Island. The first stage after a period of total thermal annealing (when the samples were above 1208C) involved Late Triassic cooling (,230 to 200 Ma) and is followed by a period of steady cooling through the whole apatite partial annealing zone (PAZ, 60–1208C) to minimum temperature in Paleocene/Early Eocene. The next stage was the maximum burial of sedimentary rocks in the Eocene (,35 Ma, 1.1–1.8 km) and the final cooling and uplift of Seymour Island sedimentary rocks at ,35 to 20 Ma.

  • 1. the Western Iberia Margin: a Geophysical and Geological Overview1
    Whitmarsh, R.B., Sawyer, D.S., Klaus, A., and Masson, D.G. (Eds.), 1996 Proceedings of the Ocean Drilling Program, Scientific Results, Vol. 149 1. THE WESTERN IBERIA MARGIN: A GEOPHYSICAL AND GEOLOGICAL OVERVIEW1 L.M. Pinheiro,2 R.C.L. Wilson,3 R. Pena dos Reis,4 R.B. Whitmarsh,5 A. Ribeiro6 ABSTRACT This paper presents a general overview of the geology and geophysics of western Iberia, and in particular of the western Portuguese Margin. The links between the onshore and offshore geology and geophysics are especially emphasized. The west Iberia Margin is an example of a nonvolcanic rifted margin. The Variscan basement exposed on land in Iberia exhibits strike- slip faults and other structural trends, which had an important effect on the development, in time and space, of subsequent rift- ing of the continental margin and even perhaps influences the present-day offshore seismicity. The margin has had a long tec- tonic and magmatic history from the Late Triassic until the present day. Rifting first began in the Late Triassic; after about 70 Ma, continental separation began in the Tagus Abyssal Plain. Continental breakup then appears to have progressively migrated northwards, eventually reaching the Galicia Bank segment of the margin about 112 Ma. Although there is onshore evidence of magmatism throughout the period from the Late Triassic until 130 Ma and even later, this was sporadic and of insignificant vol- ume. Important onshore rift basins were formed during this period. Offshore, the record is complex and fragmentary. An ocean/ continent transition, over 150 km wide, lies beyond the shelf edge and is marked on its western side by a peridotite ridge and thin oceanic crust characterized by seafloor spreading anomalies.

  • Stegosaurian Footprints from the Morrison Formation of Utah and Their Implications for Interpreting Other Ornithischian Tracks Gerard D
    Stegosaurian footprints from the Morrison Formation of Utah and their implications for interpreting other ornithischian tracks Gerard D. Gierliński and Karol Sabath Polish Geological Institute, Rakowiecka 4, 00-975 Warsaw, Poland. e-mail: [email protected] ABSTRACT - The supposed stegosaurian track Deltapodus Whyte & Romano, 1994 (Middle Jurassic of England) is sauro- pod-like, elongate and plantigrade, but many blunt-toed, digitigrade, large ornithopod-like footprints (including pedal print cast associated with the manus of Stegopodus Lockley & Hunt, 1998) from the Upper Jurassic of Utah, better fit the stego- saurian foot pattern. The Morrison Formation of Utah yielded other tracks fitting the dryomorph (camptosaur) foot pattern (Dinehichnus Lockley et al., 1998) much better than Stegopodus. If the Stegopodus pedal specimen (we propose to shift the emphasis from the manus to the pes in the revised diagnosis of this ichnotaxon) and similar ichnites are proper stegosaur foot- prints, Deltapodus must have been left by another thyreophoran trackmaker. Other Deltapodus-like (possibly ankylosaurian) tracks include Navahopus Baird,1980 and Apulosauripus Nicosia et al., 1999. Heel-dominated, short-toed forms within the Navahopus-Deltapodus-Apulosauripus plexus differ from the gracile, relatively long-toed Tetrapodosaurus Sternberg, 1932, traditionally regarded as an ankylosaurian track. Thus, the original interpretation of the latter as a ceratopsian track might be correct, supporting early (Aptian) appearance of ceratopsians in North America. Isolated pedal ichnites from the Morrison Formation (with a single tentatively associated manus print, and another one from Poland) and the only known trackways with similar footprints (Upper Jurassic of Asturias, Spain) imply bipedal gait of their trackmakers. Thus, problems with stegosaur tracks possibly stem from the expectation of their quadrupedality.

Even though it is a small-scale coast, unique geological and geomorphological features are found. It is well-known due to its international stratigraphic relevance given by the establishment of two stratotypes. The rocks of the region are well exposed along the shore, the archaeological patrimony, the cultural heritage and the biodiversity complete the region with high quality, and provide a global classroom. It is a catalogue of scientific, touristic and educational values that is being used for a long time. Because of all this became officially by UNESCO an Aspiring Jurassic Geopark of Figueira da Foz in 2018. Keywords: Aspiring Geopark; Figueira da Foz; Jurassic; culture; Mezo-Cenozoic; GSSP; ASSP 1.

  • Assessment of Undiscovered Oil and Gas Resources of the Lusitanian Basin Province, Portugal, 2016 Using a Geology-Based Assessment Methodology, the U.S
    National and Global Petroleum Assessment Assessment of Undiscovered Oil and Gas Resources of the Lusitanian Basin Province, Portugal, 2016 Using a geology-based assessment methodology, the U.S. Geological Survey assessed mean undiscovered, technically recoverable resources of 121 million barrels of oil and 212 billion cubic feet of gas in the Lusitanian Basin Province, Portugal. Introduction –10° –9° The U.S. Geological Survey (USGS) completed an assessment of undiscovered, technically recoverable oil and gas resources within the Lusitanian Basin Province, a geologically complex area of approxi- 40° mately 20,000 square kilometers along the western margin of Portugal (fig. 1). The Lusitanian Basin represents one of the extensional basins Coimbra formed during the initial stages of Mesozoic Tethyan and Atlantic rifting that preceded the opening of the north-central segment of the T Atlantic Ocean. Four phases of Mesozoic extension, two phases of UL FA ATLANTIC OCEAN RÉ Cenozoic compression, and salt movement are recorded in the rocks NAZA of the Lusitanian Basin, resulting in a complexly structured, compart- mentalized basin with several subbasins (Rasmussen and others, 1998; Alves and others, 2003; dos Reis and others, 2014a). Organic-rich, thermally mature petroleum source rocks are present in (1) Lower PORTUGAL Jurassic Brenha Formation shales (dos Reis and others, 2014b) and 39° Santarém possibly present in (2) Silurian shales in the northern part of the basin (Uphoff, 2005). Geologic Models for Assessment LISBON For the Lusitanian Basin Province, the USGS defined the Paleozoic–Mesozoic Composite Total Petroleum System (TPS) 0 25 50 MILES and the Lusitanian Basin Conventional Reservoirs Assessment Unit Setúbal (AU) within this TPS.
