Sin embargo, sus faunas marinas están todavía poco documentadas. En este trabajo se presentan los resultados de un primer estudio sobre los macrofósiles marinos del Eoceno medio–superior (Luteciense–Bartoniense–Priaboniense) de Navarra de la colección paleontológica de Máximo Ruiz de Gaona, investigador cuyos estudios sobre la geología y paleontología de este territorio constituyen una referencia histórica obligada. Los fósiles descritos provienen de las formaciones margosas del Eoceno de la cuenca de Pamplona y de la Formación Calizas de Urbasa-Andia y niveles suprayacentes, en el área de Estella-Urbasa, al oeste de la falla de Pamplona. Algunos de los especímenes estudiados provienen de afloramientos ya desaparecidos, circunstancia que aumenta el interés de la conservación y estudio de esta colección. Además, los ...

Mosasaurus sp., is here reattributed to a tylosaurine. It may belong to Tylosaurus, a nearly cosmopolitan genus known from the Santonian-Maastrichtian. This is the first occurrence of a tylosaurine mosasaurid in the Iberian Peninsula. Moreover, it corresponds to the southernmost occurrence of this clade in the northern margin of the Mediterranean Tethys. ylosaurinae fossils are known from North America, Europe, New Zealand, Antarctica, Africa and Asia, but remain unknown from the southern Mediterranean Tethyan margin and from tropical palaeolatitudes.

We describe a newsubfamily of Dynomenidae, comprising the middle-Upper Cretaceous Graptocarcinus and the Upper Jurassic Cyclothy-reus. Graptocarcininae n. subfam. shows a primitive configuration of the abdomen and an abdominal holding mechanismthat is similar to that of the Acanthodromiinae. Recognition of this ancient extinct subfamily confirms that the Dynomenidae is amongst the most basal brachyuran families.

La mayor parte de sus formaciones geológicas están constituidas por rocas sedimentarias, con algunas series de gran extensión y potencia. Estas características explican su importante registro fósil, convirtiéndola en un gran archivo de paleobiodiversidad o biodiversidad histórica. Los mares y ecosistemas continentales del Paleozoico cuentan con niveles fosilíferos de invertebrados (1) y plantas vasculares (2) en los macizos de Aldude-Kintoa y Orotz-Betelu. Los afloramientos del Jurásico de Urdaibai y Aralar corresponden en su mayor parte a depósitos marinos de facies nerítica y contienen fósiles de moluscos, braquiópodos y otros invertebrados (3). Las formaciones geológicas del Cretácico y Paleógeno so...

El estudio del Registro fósil —objeto de la ciencia de la Paleontología— permite analizar diferentes procesos de cambio que requieren tiempo geológico (tomada como unidad ~ 1 millón de años), no detectables en el tiempo ecológico, tales como (1) el origen e historia evolutiva de los grupos de organismos, —in-cluida la de nuestra propia familia humana—; (2) los cambios de biodiversidad a lo largo de la historia de la Tierra y procesos relacionados, como la variable duración de las especies o la posible relación entre el reemplazamiento de las mismas y determinados ciclos astronómi-cos; o (3) las respuestas ...

Geologically, Laño and the adjacent region are set on the southern limb of the South-Cantabrian Synclinorium (SE Basque-Cantabrian Region, northern Iberian Peninsula). The Laño sites were discovered in 1984; thousands of bones and teeth, including microfossils, have been collected during the prospection in the field and excavation campaigns. The vertebrate remains occur at two different stratigraphic horizons within a continental to shallow marine succession of Late Campanian-Maastrichtian age. The lower horizon contains the Laño 1 and Laño 2 sites, whereas the upper horizon contains the Albaina site. In the Laño sites, three fossiliferous beds (called L1A, L1B and L2) are known within an alluvial system composed mainly of fluvial sands and silts. The sedimentary structures are consistent with channel areas within an extensive braided river system. Based mainly on stratigraphic correlations, the fluvial beds of Laño are regarded as Late Campanian to Early Maastrichtian in age. These deposits have yielded a very diverse vertebrate assemblage, which consists of nearly 40 species, including actinopterygians, lissamphibians, lepidosaurs, turtles, crocodyliforms, dinosaurs, pterosaurs, and mammals. Seven genera and ten species have been erected to date in Laño. With reference to the marine vertebrate association of Albaina, it consists of at least 37 species, including sharks and rays, actinopterygians, mosasaurids, and plesiosaurs. Two genera and species of rhinobatoids (family indet.) and two new species of rhinobatids have been erected in Albaina. The fossil association indicates a Late (but not latest) Maastrichtian age. Recently, isolated turtle and dinosaur fossils have been discovered in the sublittoral beds of Albaina. The Laño quarry is one of the most noteworthy Campanian-Maastrichtian vertebrate localities of Europe by its taxonomic diversity, and provides useful information about the composition and affinities of both continental and marine vertebrate faunas from the latest Cretaceous of southwestern Europe.

A new specimen, which consists of a fragment of skull with articulated portions of the maxilla and prefrontal, from the Campanian of Navarre is described here. This material is assigned to Prognathodon cf. sectorius on the basis of dental features. It constitutes the only cranial remain and the most significant mosasaurid fragment known to date in the Iberian Peninula. P. sectorius was previously recorded from the Maastrichtian of New-Jersey and The Netherlands.

They consist of an incomplete hadrosauroid femur, and two partial plates of turtles, one belonging to a Pleurodira (Bothremydidae), the other one to an indeterminate taxon, probably corresponding to a Pan-Cryptodira. They are the first dinosaur and turtle remains found in the Late Maastrichtian sublittoral beds of Albaina. Other components of this shallow marine vertebrate fauna are selachians (sharks, rays), actinopterygians (pycnodonts, teleosts) and marine reptiles (mosasaurids, plesiosaurs). The Albaina femur is one of the few hadrosauroid remains from the Late Maastrichtian of Europe found in marine environments, and the first one described from this kind of deposits in the Iberian Peninsula. The histological structure of the bone indicates that it belongs to an immature individual of small size.

Numerous teeth of Elasmobranchii and Actinopterygii are the most prevailing fossil material, although scarce teeth of marine reptiles (Mosasauridae) and dinosaurs (Hadrosauridae) also occur. The presence of one hadrosaurian tooth, a terrestrial taxon, constitutes the first report of ornithischians in the Valdenoceda Formation. The fossil vertebrate association of Quintanilla la Ojada is similar to that discovered in Albaina (Treviño County, Burgos), also located in the Basque-Cantabrian Region, although relatively younger in age. Both fossil sites are characterised by a mixture of taxa from the northern and southern margins of the Mediterranean Tethys (north-European and north-African outcrops).

Este libro pretende explicar, desde una óptica personal, el origen del museo y de su significativa colección de fósiles. Otro objetivo principal del libro ha sido, también, presentar en forma de catálogo sistemático, la aportación hecha por el autor a la colección paleontológica del MCNA: más de 2800 especímenes fósiles depositados durante su actuación profesional como conservador-consultor, la gran mayoría de ellos recolectados en solitario y cerca del millar en compañía de colegas de profesión, o entusiastas de la paleontología.
