De congreso virtual en el 64th Annual Meeting of the Palaeontological Association


Varios integrantes del Grupo de Biología Evolutiva de la UNED han presentado charlas y pósteres durante el congreso 64th Annual Meeting of the Palaeontological Association. Este año la PalAss 2020 se ha organizado desde Oxford y se ha celebrado virtualmente entre los días 16-18 de diciembre. A continuación os dejamos un pequeño resumen de los trabajos presentados.

Patrones ontogenéticos en el paladar de cocodrilos

En este trabajo, en el que participaron Ane de Celis, Iván Narváez, Alejandro Serrano-Martínez y Francisco Ortega, se analizó cómo varía la morfología del paladar crocodiliano a lo largo de su desarrollo, desde que son individuos juveniles hasta que son adultos. Los resultados obtenidos arrojan algunos patrones comunes de variación morfológica ontogenética, como por ejemplo el desplazamiento de los palatinos hacia el área posterior del paladar a medida que los individuos alcanzan la madurez.


Caracterización de la variabilidad intraespecífica de la tortuga Pleurosternon bullockii (Paracryptodira)

Otro de los trabajos defendido este año en la PalAss ha sido por parte de Andrea Guerrero y Adán Pérez-García, en el que se evaluó la variabilidad interindividual del estadio adulto de la tortuga mesozoica Pleurosternon bullockii, mediante la integración de dos metodologías distintas (cualitativa y cuantitativa). Los análisis revelaron que la mayor parte de la variación morfológica es explicada por polimorfismos, identificados en diversos elementos del caparazón. Asimismo, se reconocieron dos dimorfos sexuales, lo que ha permitido una aproximación a la interpretación del dimorfismo sexual por primera vez en Pleurosternidae.


Sobre la validez de la tortuga británica “Pleurosternon portlandicum

También, en la edición de este congreso, se ha presentado un segundo trabajo referente al género Pleurosternon. En este caso, se evaluó la validez específica del taxón británico apenas conocido “Pleurosternon portlandicum”, así como su atribución al género Pleurosternon. Concretamente, se revisaron las diferencias anatómicas utilizadas previamente por algunos autores para distinguir “Pleurosternon portlandicum” de la especie tipo del género Pleurosternon (es decir, Pleurosternon bullockii), reconociendo tales diferencias como producto de la variabilidad intraespecífica de Pleurosternon bullockii. Este trabajo además se ha publicado recientemente en la revista Journal of Iberian Geology.


Estudio neuroanatómico y capacidades sensoriales en la tortuga primitiva Kallokibotion bajazidi

En este trabajo, en el que participaron Marcos Martín-Jiménez, Vlad Codrea y Adán Pérez-García, se realizó un análisis detallado de la anatomía ósea y las cavidades internas del cráneo de Kallokibotion bajazidi mejor conservado hasta la fecha y un basicráneo de otro individuo, ambos procedentes del Cretácico Superior de Rumanía. A partir de las imágenes obtenidas mediante un CT-Scan, se crearon modelos tridimensionales, tanto de los huesos aislados como de las estructuras neuroanátomicas de los dos especímenes. Este estudio permitió ampliar el conocimiento sobre la anatomía craneal de la especie, apoyando su posición filogenética como taxón cercanamente relacionado con el grupo corona Testudines. Además, una comparación detallada de su neuroanatomía con otros taxones primitivos nos permitió inferir un modo de vida terrestre para Kallokibotion bajazidi.


Sobre la validez y distribución paleobiogeográfica del botremídido del Cretácico Superior de Europa “Polysternonatlanticum

El linaje de tortugas reconocido como más abundante y diverso, para los niveles del Cretácico Superior de Europa suroccidental, el de las pleurodiras Bothremydidae. Dentro de ese grupo, la especie peor caracterizada era, hasta ahora, “Polysternonatlanticum. Su atribución genérica resultaba dudosa, y carecía de una diagnosis actualizada, siendo únicamente reconocida en la localidad donde fue definida: el yacimiento de Laño, en el Condado de Treviño (Burgos). El estudio detallado de este taxón, ignorado desde la década de 1990, gracias al análisis de relativamente abundante material inédito, ha permitido incrementar notablemente el conocimiento sobre el mismo. Así, su atribución genérica ha podido ser refutada. Sin embargo, se considera válido a nivel específico, reconociéndose en otras regiones, no sólo españolas sino también de Francia.
