Curator Natural History Los Angeles County

The Natural History Museum of Los Angeles County (NHMLA) seeks a Curator (Assistant preferred, but open to all ranks) to lead its research on invertebrate paleontology and paleoecology, to oversee the growth and care of collections of NHMLA’s Department of Invertebrate Paleontology (IP), and to provide content for a variety of public programs.  More specifically, the successful candidate will conduct collection-based research in late Cenozoic marine paleoecology, with the aim of contributing to NHMLA’s program of long-term ecological change in Southern California.

NHMLA’s vast IP collection (> 7 million specimens) spans half a billion years of biological and geological evolution in Southern California.  It includes fossils of all major marine invertebrate groups as well as ichnofossils, and contains the world’s largest collection of Cretaceous-Cenozoic mollusks from the Pacific Rim, the result of a century of research by NHMLA staff and amalgamation of collections from several Southern California universities. Half of this collection consists of fossils from the Pleistocene Epoch. Of the 3.5M Pleistocene specimens, 1.5M have been digitized, allowing this long-term dataset to bear on questions of Southern California’s ecological past and present, in turn greatly augmenting the efforts of NHMLA’s coastal biodiversity initiatives by incorporating a paleontological perspective.

The successful candidate will have a record of outstanding research, excellent communication skills, and a demonstrated ability to engage the public and stakeholders.  A Ph.D., a strong record of peer-reviewed publications focusing on late Cenozoic marine invertebrate paleoecology and paleontology, and demonstrated ability to secure extramural funding are required.  Experience in managing large natural history collections and active field programs are highly desirable.  The Curator will be expected to build an active and publicly appealing research program, to lead continued improvement of the IP collections, to oversee all NHMLA’s programs on invertebrate fossils, and to supervise staff and volunteers of the IP Department.  Additionally, the successful candidate is expected to develop working relationships with local universities, mentor students and postdoctoral fellows, strengthen NHMLA’s presence in key professional and governmental networks, and maintain research through competitive grants and/or other funding from external sources.


The Curator will be expected to participate actively in a broad range of museum activities, including exhibits, education, community science programs, educator and volunteer training, public communications, media interactions, and fundraising activities.  A vision and capability to build a research program that can be integrated with NHMLA’s ongoing efforts to understand regional biodiversity, and to shape the collections and research in ways that activate both their scientific and public appeal, is paramount.

NHMLA is seeking applicants who have demonstrated experience and commitment working with a diverse community. This is a full-time position with a salary and title commensurate with experience.

Application deadline is February 15, 2019.  The starting date is July 1, 2019. Applicants should send a cover letter, vision statement, curriculum vitae, and the full contact information of at least three professional references as a single PDF document to thayden@nhm.org, Marine Invertebrate Paleoecology Curatorial Search.

Research Grants for early career paleontologists

I would like to draw your attention to the Norman Newell Grant for early career paleontologists whose deadline is Feb. 1, 2019 and fast approaching. The grant is funded by the Paleontological Society (PS) and applicants must be current members of the PS at the time of application.

Eligible applicants include paleontologists within five years of their Ph.D., who are members in good standing of the Paleontological Society. Applications are encouraged from anywhere in the world, except those from countries with economic or trade sanctions imposed by the U.S. Office of Foreign Assets Control (OFAC).

The Norman Newell grants complement the Arthur Boucot grants, and preference is therefore given to research projects in areas not covered by the Arthur Boucot grant topical areas of morphology, taxonomy, and biostratigraphy. Applicants can only apply to one of these Early Career Grants per funding year. To broaden the reach of Paleontological Society funds, recipients of a Norman Newell grant may not apply for an Arthur Boucot grant, nor may they apply for a second Norman Newell grant. Similarly, recipients of an Arthur Boucot grant may not apply for a Norman Newell grant.

Four Norman Newell grants of $5,000 each will be made each year. Awards are made directly to individuals and not to institutions, and awards cannot be used for salary, stipends, tuition, or institutional overhead.

Application instructions (including downloadable form and details on two required letters of recommendation) and complete grant details are available at http://paleosoc.org/grants-and-awards/paleontological-society-newell-grant/
Information for the complementary Paleontological Society Arthur James Boucot Research Grants for early career paleontologists (with the same
deadline) is available at

La impronta de cambios climáticos Jurásicos en la geología turolense, recogida en un estudio de la Universidad de Zaragoza

La revista científica Journal of Iberian Geology publicará en su primer número del año 2019 un artículo que analiza e interpreta las evidencias sedimentológicas que los cambios climáticos de finales del Jurásico (Kimmeridgiense-Titoniense, hace 153-151 millones de años) dejaron en la geología de la zona comprendida entre los pueblos turolenses de Galve, Aguilar del Alfambra y Monteagudo del Castillo. Además, un estudio que complementa los datos expuestos en este trabajo será publicado en Geogaceta, cuyos resultados fueron presentados el pasado mes de noviembre en una de las sesiones científicas de la Sociedad Geológica de España en El Hierro (Canarias).
El estudio, encabezado por los investigadores Jorge Val, Marcos Aurell y Beatriz Bádenas, del Dpto. de Ciencias de la Tierra de la Universidad de Zaragoza, incluye las siguientes claves de interés para el estudio de la zona:

•    Ciclos en la sucesión sedimentaria: El estudio ha revelado que se formaron por la alternancia entre etapas de climas húmedos, en los que llegaba más aporte fluvial de sedimentos a la cuenca (materiales siliciclásticos) y climas más áridos, que favorecían la sedimentación de depósitos carbonatados.  Tras una calibración temporal de los materiales, mediante el análisis de isótopos estables de estroncio y la datación de fósiles microscópicos (foraminíferos), se estima que estos ciclos tenían una duración aproximada de 400.000 años. Esta edad coincide con el parámetro de edad de las variaciones en la excentricidad de la órbita terrestre: La órbita en la que el planeta gira alrededor del Sol modifica su forma según ciclos de 400.000 años, haciendo que la Tierra gire a una mayor o menor distancia del Sol. Esto determina la influencia de la radiación solar sobre el clima terrestre, y a su vez, lo hizo sobre la geología turolense.

•    Entre Aragosaurus ischiaticus y Galvesaurus herreroi hubo más de 10 millones de años de historia geológica: Los investigadores de la Universidad de Zaragoza han determinado que la formación geológica Villar del Arzobispo, objeto de este estudio, es muy diferente geológicamente con respecto a las que se sitúan sobre ella: las formaciones Aguilar del Alfambra y Galve.
La calibración temporal de los afloramientos en que se encontraron los restos de estos dinosaurios delimita la edad de Galvesaurus herreroi aproximadamente entre los 153 y 151 millones de años (Edad Kimmeridgiense-Titoniense), mientras que hay datos que confirman que Aragosaurus ischiaticus vivió en al final del Berriasiense, un periodo más reciente que concluyó hace 140 millones de años, lo cual los alejaría en el tiempo.

•    Periodo de gran actividad tectónica entre las formaciones Villar del Arzobispo y Aguilar del Alfambra: Las diferencias en el medio sedimentario de ambas formaciones se explican por una actividad tectónica vigorosa, que implica la formación de una discordancia observable en algunas localidades. El estudio de los afloramientos en Aguilar del Alfambra aporta valiosos datos que los efectos de las fallas que actuaron durante el depósito de estas unidades.

La zona objeto de estudio es conocida, además de por la calidad de sus afloramientos geológicos, por albergar el Parque Geológico de Galve, que celebra su 25 aniversario, y por ser el lugar donde se encontró, hace 60 años, el primer dinosaurio que se definió en España: Aragosaurus ischiaticus.

Portugalosuchus, el origen de los cocodrilos modernos

Una nueva especie de cocodrilomorfo eusuquio, Portugalosuchus  azenhae, descrita en Portugal por los miembros de las Universidades Nova de Lisboa y de Coimbra, Octávio Mateus, el Aragosaurero Eduardo Puértolas Pascual y Pedro Callapez, podría cambiar lo que los científicos pensaban sobre el origen de Crocodylia. El cráneo y la mandíbula, que fueron recuperados por Matilde Azenha cerca de la localidad de Tentúgal (Portugal), de ahí el nombre de la especie, se podrán visitar en el Museu da Lourinhã a pocos kilómetros al norte de Lisboa.

El clado Crocodylia, en el que se incluyen todas las especies de aligátores, caimanes, gaviales y cocodrilos actuales, así como otras especies extintas, no se conocía en el registro fósil hasta el Campaniense (Cretácico Superior, entre 83 y 72 millones de años). Antes del Campaniense habitaban la Tierra otros linajes extintos de cocodrilomorfos. Portugalosuchus es del Cenomaniense (hace 95 millones de años), y de acuerdo a los análisis realizados podría estar fuertemente emparentado o incluso pertenecer al clado Crocodylia, adelantando la aparición de los primeros cocodrilianos unos 20 millones de años. Esto situaría a Portugalosuchus como una de las especies de Eusuchia más antiguas del registro fósil y posiblemente el cocodriliano más antiguo descubierto hasta el momento. Además, su descubrimiento ayudaría a llenar el vacío de registro fósil de vertebrados continentales del Cretácico “medio”, que es muy escaso a nivel mundial, ayudando resolver diversas cuestiones filogenéticas y paleobiogeográficas.


Este cráneo y la mandíbula presentan una serie de caracteres no vistos anteriormente en el registro fósil, permitiendo su asignación a una nueva especie. Una de sus características más importantes es la presencia de una pequeña apertura en el lateral de la mandíbula. Este tipo de apertura, que sirve para inserciones musculares que participan en el movimiento de la mandíbula, es típica de varios grupos de cocodrilomorfos primitivos, pero sobre todo caracteriza al clado Crocodylia, en los que suele aparecer bastante desarrollada. La presencia de una pequeña apertura en Portugalosuchus podría representar uno de los estados ancestrales o primitivos de esta estructura en Crocodylia arrojando luz sobre el origen y evolución del grupo que incluye a todas las especies que habitan en la actualidad.
