- PublicationRevision of medium-sized Cricetidae from the Miocene of the Daroca-Villafeliche area in the Calatayud-Teruel basin (Zaragoza, Spain)(Universidad Complutense de Madrid, Servicio de Publicaciones, 2003) Van der Meulen, Albert Jan; Peláez-Campomanes de Labra, Pablo; Daams, RemmertRevision of Democricetodon (excluding D. sulcatus and D. cf gaillardi), Fahlbuschia, Pseudofahlbuschia and Renzimys from the Aragonian type area (Spain) results in the synonymization of the four genera, Democricetodon prevailing according to the rules of priority. Democricetodon decipiens is synonymized with D. corcolesi, D. darocensis with D. larteti, and Renzimys bilobatus with D. crusafonti. One new species of Democricetodon (D. moralesi n.sp.) is defined.Two partly contemporaneous evolutionary lineages are recognized: the Democricetodon hispanicus - D. lacombai lineage (D. hispanicus-D. moralesi n.sp.-D. jordensi-D. lacombai) and the Democricetodon franconicus - D. crusafonti lineage (D. franconicus-D. koenigswaldi-D. larteti- D. crusafonti). [RESUMEN] La revisión realizada del material de los géneros Democricetodon (excluidos D. sulcatus y D. cf gaillardi), Fahlbuschia, Pseudofahlbuschia and Renzimys del área tipo del Aragoniense (España) ha dado como resultado la sinonimia de los cuatro géneros, siendo Democricetodon el que tiene la prioridad. Democricetodon decipiens se ha sinonimizado con D. corcolesi, D. darocensis con D. larteti, y Renzimys bilobatus con D. crusafonti. Una nueva especie de Democricetodon (D. moralesi n.sp.) ha sido definidas. Dos líneas evolutivas, parcialmente contemporáneas han sido reconocidas: La línea Democricetodon hispanicus - lacombai (D. hispanicus-D. moralesi n.sp.-D. jordensi-D. lacombai) y la línea Democricetodon franconicus - D. crusafonti (D. franconicus-D. koenigswaldi-D. larteti- D. crusafonti).
- PublicationUp-to-date Spanish continental Neogene synthesis and paleoclimatic interpretation(Sociedad Geológica de España, 1993) Calvo Sorando, José Pedro; Daams, Remmert; Morales, J.; López Martínez, Nieves; Agustí, J.; Anadón, P.; Armenteros, I.; Cabrera, L.; Civis Llovera, Jorge; Corrochano, A.; Díaz Molina, M.; Elizaga, E.; Hoyos, M.; Martín-Suárez, E.; Martínez, J.; Moissenet, E.; Muñoz, A.; Pérez-García, A.; Pérez-González, Alfredo; Portero, J.M.; Robles, F.; Santisteban, C.; Torres, T.; Meulen, A.J. van der; Vera, J.A.; Mein, P.A synthesis of the Spanish continental Neogene is presented by designing an integrated correlative chart of the Neo" gen-e "succes"Siuns-ofthe "lberian-PeninsuIa-. -Ninemain-sedimentary-breaks-have-been -distinguished-in-most-of-the "basins. They are considered a valuable criteria for correlation as they occur in similar time intervals from basin to basin. The determined sedimentary breaks occur in the Agenian, Ramblian, Middle Aragonian, Late Aragonian, Late Vallesian, Middle Turolian, Late Turolian, Late Ruscinian-Early Villafranchian, and Villafranchian ages. The larger interior basins (Ebro, Tajo, Duero) show a fairly complete Neogene sedimentary record in which the aboye mentioned sedimentary breaks are usually well recognized. A good correlation may be established from basin to basin. Likewise, there is a fairly good correlation among the Upper Miocene-Pliocene sedimentary record of basins spreading out in Levante and southeastern Spain. However, the correlation is not as c1ear in those basins located within the Iberian and Catalan Coastal Ranges, which usually do not show a similar sedimentary pattern. The comparison between Neogene stratigraphic logs in most of the Spanish continental basins and the pattern of global events from currentIy accepted Cenozoic Cyc1e Charts allows recognition of chronological coincidences, especially with regard to the age of seven major sedimentary ruptures (those developed at about 24.5 Ma, 22 Ma, 16 Ma, 13.5 Ma, 9.5 Ma, 5.5 Ma, 3.3 Ma). Evolutionary sedimentary trends in both offshore Mediterranean areas and inland peripheral zones of the Iberian Peninsula show also striking coincidences regarding the chronology of major sedimentary breaks observed in continental successions. Paleoc1imatic curves for the Spanish continental Neogene display four relative temperature peaks indicative of warm c1imatic conditions (Late Agenian, Early-Middle Aragonian, Vallesian-Turolian, and Late Villafranchian) as well as five relatively dry periods (Early Ramblian, Middle-Late Aragonian, Middle Turolian, Late Ruscinian, and Middle Villafranchian ages).
- PublicationThe earliest mammal of the Euopean Paloecene: the multituberculate Hainina(The Paleontological Society, 2000) Peláez-Campomanes de Labra, Pablo; López Martínez, Nieves; Álvarez Sierra, María Ángeles; Daams, RemmertABSTRACT—A new species of multituberculate mammal, Hainina pyrenaica n. sp. is described from Fontllonga-3 (Tremp Basin, Southern Pyrenees, Spain), correlated to the later part of chron C29r just above the K/T boundary. This taxon represents the earliest European Tertiary mammal recovered so far, and is related to other Hainina species from the European Paleocene. A revision of the species of Hainina allows recognition of a new species, H. vianeyae n. sp. from the Late Paleocene of Cernay (France). The genus is included in the family Kogaionidae Ra˜dulescu and Samson, 1996 from the Late Cretaceous of Romania on the basis of unique dental characters. The Kogaionidae had a peculiar masticatory system with a large, blade-like lower p4, similar to that of advanced Ptilodontoidea, but occluding against two small upper premolars, interpreted as P4 and P5, instead of a large upper P4. The endemic European Kogaionidae derive from an Early Cretaceous group with five premolars, and evolved during the Late Cretaceous and Paleocene. The genus Hainina represents a European multituberculate family that survived the K/T boundary mass extinction event
- PublicationHipparion dispersal in Europe: magnetostratigraphic constraints from the Daroca area (Spain).(Universidad Complutense de Madrid, Servicio de Publicaciones, 2003) Garcés, Miguel; Krijgsman, Wout; Peláez-Campomanes de Labra, Pablo; Álvarez Sierra, María Ángeles; Daams, RemmertThe Nombrevilla section in the Calatayud-Daroca basin (Central Spain) bears one of the best late Aragonian to early Vallesian large and small vertebrate fossil records in Europe, including important findings of the equid Hipparion. Magnetostratigraphic dating of the Nombrevilla section thus provides further age constraints on the timing of Hipparion dispersal in Europe, a bioevent which defines the base of the Vallesian mammal stage. Correlation of the Nombrevilla magnetic polarity stratigraphy to the geomagnetic polarity time scale is supported by the identification of the characteristic long normal chron C5n in the upper half of the section, in association with early Vallesian (early late Miocene) fossils. The classic mammal fossil site Nombrevilla 1, recording the earliest occurrence of Hipparion, correlates to the lower third of chron C5n, and yields an interpolated age of about 10.7-10.8 Ma. This age is in agreement with magnetostratigraphic dating of earliest occurrences in Siwaliks of Pakistan and some 40Ar/39Ar ages of Mediterranean sites. The youngest pre-Hipparion large mammal fossil record corresponds to Nombrevilla 9, a site wich approximately correlates to chron C5r.1n, at about 11.1 Ma. This result is nearly in conflict with the data from the Vallès-Penedès, where a Hipparion bearing site is correlated to the same chron. In addition, Nombrevilla 9 yields a small mammal assemblage which corresponds to local zone H, a biozone wich was classically correlated to the lower Vallesian. This implies a diachrony of about 300 kyr between the lower boundary of zone H and the first occurrence of Hipparion (base of the Vallesian) in the Calatayud-Daroca basin. Correlation of the Aragonian levels of Nombrevilla 2, 3 and 4 is not yet certain and would require further downward extension of the magnetostratigraphy in a neighbouring section. Nevertheless, we can confidently say these localities are younger than 11.6 Ma. [RESUMEN] La sucesión estratigráfica de Nombrevilla en la cuenca de Calatayud-Daroca (Cordillera Ibérica) contiene uno de los más ricos registros de macro y microvertebrados fósiles del tránsitoAragoniense/Vallesiense. El estudio magnetoestratigráfico de Nombrevilla aporta nuevos datos sobre la cronología de la aparición de Hipparion, un bioevento que define la base del piso Vallesiense. La correlación con la escala de tiempo de polaridad geomagnética está basada en la identificación de C5n, un cron de más de 1 Myr de polaridad normal que es característico del Mioceno superior. La localidad clásica Nombrevilla 1, que representa el registro más antiguo de Hipparion, se correlaciona con el tercio inferior del cron C5n, y le corresponde una edad interpolada de 10.7-10.8 Ma. Este dato se corresponde muy bien con la datación magnetoestratigráfica del mismo bioevento en Siwaliks (Pakistán) así como las dataciones radiométricas 40Ar/39Ar en otras localidades de la región mediterránea. La localidad con macrovertebrados más alta sin Hipparion en la serie de Nombrevilla es Nombrevilla 9, que se correlaciona aproximadamente con el cron C5r.1n (11.1 Ma). Este resultado no se corresponde exactamente con los resultados del Vallès-Penedès, donde una edad muy similar se obtiene para la primera aparición de Hipparion. Aparte, Nombrevilla 9 es particularmente significativa puesto que muestra una asociación de microvertebrados correspondiente a la zona local H, que clásicamente se había identificado con el Vallesiense inferior. Los nuevos datos señalan una diacronía de cerca de 300 kyr. entre el limite inferior de la zona H y la aparición de Hipparion en Calatayud-Daroca. La correlación de las localidades del Aragoniense superior Nombrevilla 2, 3 y 4 es relativamente incierta, si bien es seguro que se encuentran en la parte superior del cron C5r, con una edad no menor que 11.6 Ma.
