Nos ha llegado información de un interesante congreso sobre equinodermos
paleozoicos que se va a celebrar en Zaragoza el próximo año. Os
adjuntamos la información básica y la primera circular. Tiene muy buena
pinta esta reunión.
We are pleased to announce a Palaeozoic Echinoderm Conference that will
take place in Zaragoza, Spain in June 2015. This conference will also
celebrate the career of our colleague and friend Dr. Andrew Smith, a
world-renowned specialist in echinoderms who retired in late 2012.
Andrew
spent the majority of his career at the Natural History Museum of
London (1982–2012), where he carried out remarkable research on a
diverse range of topics, including echinoid taxonomy, Phanerozoic marine
diversity and primitive echinoderms.
The conference will be
focused on Palaeozoic echinoderm communities, a major area of interest
for Andrew. Contributed presentations will review the current state of
knowledge for a range of groups, highlighting recent advances, but more
importantly identifying topics of uncertainty and possible future
research paths. Andrew will provide a plenary talk about the earliest
steps of echinoderm evolution. In addition, there will be short
workshops on Spanish fossil material and new analytical techniques for
studying early echinoderms (e.g. tomography, computer modelling and 3-D
printing). Finally, there will be a field trip to visit several
important Palaeozoic outcrops in northern Spain, which have yielded a
wide variety of fossil echinoderms.
The presentations and
workshops will take place in Zaragoza. The field trip will take place
close to Zaragoza (Iberian Chains) and in the north western part of
Spain, between the cities of León and Oviedo (Cantabrian Mountains).
Details of the field trip will be provided in the second circular, but
we propose to visit Cambrian, Ordovician, Silurian and Devonian
outcrops.
If you want to keep receiving information about the
meeting let us know, please. For general questions about the meeting or
scientific sessions, please contact Samuel Zamora (s.zamora@igme.es).[Descarga el PDF relacionado]
Un nuevo reptil acuático del Triásico de China, con una adaptación para
alimentarse, muy especializada, acaba de ser descrito por nuestros
colegas, los paleontólogos chinos Long Cheng, Xiao-Hong Chen, Qing-Hua
Shang y Xiao Chun Wu en la importante revista científica
Naturwisenchaften. El reptil, un diápsido, procede del Triásico de
Luoping (Yunnan), unos 270 millones de años.
El estudio
geológico indica que el yacimiento donde se encontró se deposito con
sedimentos marinos costeros, en cuyos niveles se encuentran otros
fósiles de reptiles marinos como ictiosaurios, sauropterigios de
distintos tipos, protorosauros y archosauriformes. También hay numerosos
invertebrados como crustáceos, miriápodos, bivalvos, gasterópodos,
belemnites, equinodermos, braquiópodos…Un mar rico en alimentos. La
diversidad de esta fauna queda también reflejada por la variedad de
mecanismos de alimentación que se encuentran entre los grupos de
reptiles Luoping.
El reptil del que queremos hablar en esta nota
es muy peculiar. Sus dientes se distribuyen como los dientes de un
peine. Más de 175 dientes pleurodontos (están soldados al hueso) se
encuentran en cada rama tanto derecha como izquierda de las mandíbulas y
de los maxilares. Los maxilares en lugar de estar soldados en la parte
medial, están abiertos, y en ambos bordes también se encuentran dientes.
Un cráneo realmente singular como se puede ver en la fotografía.
Además,
los dientes son como finas agujas. Altos y delicados. En esto se
parecen a los de algunos reptiles voladores que también se alimentaban
seguramente por filtración de los alimentos en el agua. En contraste con
los finos dientes, las mandíbulas son masivas, lo que indican una gran
fortaleza y que probablemente tenían fuertes musculaturas para abrirlas y
moverlas hacia atrás.
Esto nos indica que Atopodentatus unicus,
que así es el nombre que le han puesto a este peculiar reptil diápsido
marino (haciendo referencia a la dentición peculiar y única entre los
vertebrados) podría haber sido un vertebrado que araba el fondo marino
en busca de pequeños organismos bentónicos. Además los dedos de Atopodentatus unicus
terminan en pezuñas, esto junto con otras características anatómicas
del esqueleto permite afirmar que sería capaz tanto de nadar como de
caminar sobre tierra, planicies de marea e islas de arena en la zona
intermareal.
El holotipo, un esqueleto casi completo, de algo
más de dos metros desde la cabeza a la cola, se encuentra en el
Instituto de Geología y recursos minerales de Wuhan, en China.

SALINAS DE INTERIOR. OTROS MODELOS DE EXPLOTACIÓN DE SAL, DE LA
PREHISTORIA A LA ACTUALIDAD.
VIERNES 14 DE FEBRERO 20:30 H. RESTAURANTE BODEGA EL CARRETERO.
CHICLANA DE LA FRONTERA.
(Calle Sor Ángela de la Cruz, 26)
El I Ciclo Internacional de BARferencias es un evento promovido por ERA
Cultura, en el que se realizan conferencias de corte distentido que se
llevarán a cabo fuera de los muros académicos, en los bares, a lo
largo de distintas ciudades como: Madrid, Cuenca (Ecuador), Zafra
(Badajoz), Córdoba, Cantabria y Chiclana de la Frontera.
Las BARferencias tienen una temática que gira en torno a la historia y
la arqueología pero con muy variados contenidos, algo natural teniendo
en cuenta la variedad geográfica. Es por ello que podemos encontrar
desde aspectos de la vida cotidiana del mundo romano a excavaciones
realizadas en el cerro Huyacán de Ecuador.
El viernes 14 de febrero se realizará la primera de un ciclo de 3
conferencias, en chiclana de la Frontera, que será impartida por el Dr.
Santiago Valiente Cánovas, Catedrático de Artes Plásticas y Diseño
en la Escuela Superior de Conservación y Restauración de Bienes
Culturales de Madrid. en el restaurante bodega El Carretero a las 20:30,
bajo el título "Salinas de Interior. Otros modelos de explotación de
sal desde la prehistoria hasta la actualidad." Con ello las Barferencias
pretenden acercar a la ciudadanía de Chiclana de la Frontera, aspectos
no tan conocidos sobre las formas de extracción y explotación de sal,
con tanta tradición en la ciudad. En la actualidad Santiago Valiente
Cánovas está gravitando sus estudios desde la meseta, en yacimientos
tan emblemáticos como las salinas de Espartinas (Ciempozuelos), a la
provincia de Cádiz, obteniendo datos novedosos de áreas de
explotación de sal de interior de nuestra provincia.

La imagen una magnífica reconstrucción de Carolowilhelmina
realizada por Víctor Selles. Os iremos contando próximamente más de este
paleoilustrador. A lo que vamos, Carolowilhelmina es un cráneo fósil de
“pez” placodermo que solo se ha encontrado en el Devónico aragonés. La
próxima exposición permanente del Museo de Ciencias Naturales de la
Universidad de Zaragoza va a exponer piezas únicas en el mundo, una de
ellas es este cráneo. Las circunstancias del descubrimiento de Carolowilhelmina
merece entrar en la historia de la Paleontología aragonesa por la
constancia del paleontólogo Peter Carls en la recuperación de este
fósil. Os contamos un poco la historia.
Hace 400 millones de
años lo que hoy conocemos como Aragón (Norte de España) estaba sumergido
en unos mares repletos de vida situados en el hemisferio sur de la
Tierra. El Devónico es un periodo de tiempo especialmente rico en
fósiles de invertebrados marinos en Aragón. Hay yacimientos conocidos
mundialmente, pero poco espectaculares para el gran público. Los fósiles
que se encuentran son de animales de grupos fósiles como los trilobites
o con representantes actuales como cefalópodos o los corales, pero muy
diferentes morfológicamente. En ese mundo vivió Carolowilhelmina.
Peter
Carls es un investigador alemán que empezó a hacer su tesis doctoral en
la década de los 1960 en paleontología del Paleozoico en el sur de la
provincia de Zaragoza y el norte de Teruel. Se quedó encantado de las
gentes y de los fósiles de la zona por lo que durante 40 años volvió
cada verano, lo que permitió descubrir un montón de especies nuevas.
Llego a ser catedrático en la Universidad de Braunschweig, pero nunca
faltó a su cita anual por las tierras aragonesas. Fue el descubridor de
una de las maravillas del Museo, como es un cráneo de un placodermo
llamado Carolowilhelmina geognostica. Peter no buscaba fósiles de
peces, sino que lo encontró por casualidad. En su investigación
disgregaba roca caliza en busca de microfósiles llamados conodontos.
En
una de las muestras apareció un fragmento enorme de un cráneo. Una vez
preparado se dio cuenta que faltaba una parte importante. Durante 15
años volvió al mismo afloramiento donde había encontrado el primer
resto… y finalmente recuperó el fragmento que faltaba. Fueron necesarios
muchos años de preparación del fósil para disgregar con ácido la roca
que lo rodeaba. Carolowilhelmina es un cráneo prácticamente
completo de un “pez” placodermo que podría llegar a tener unos dos
metros de longitud. Su principal característica es la protuberancia
situada en la parte anterior del cráneo semejante a las que presentan
los peces espadas actuales, aunque solo se trata de una convergencia
evolutiva. Carolowilhelmina pertenece a un grupo totalmente
extinguido que son los placodermos. Se trata de unos “peces” con el
cuerpo cubierto de placas duras que les protegía el cuerpo. Algunos
alcanzaron tamaños gigantescos, siendo los auténticos reyes de los mares
del Devónico.
