               <mods:abstract>This paper discusses the extinction pattern of the Pliensbachian-Toarcian boundary (PTB) ostracod assemblages at the Almonacid de la Cuba
section (Cordillera Ibérica, NE Spain), which has been recently proposed as auxiliary boundary stratotype for the PTB. The ostracod record shows
that the main Early Jurassic ostracod extinction event occurred not at the end of the Pliensbachian, but near the top of the Mirabile ammonite
Subzone, Tenuicostatum ammonite Zone (Early Toarcian). On the basis of the evaluation of PTB ostracod record, a new causal explanation for the
Early Toarcian ostracod turnover is proposed. This paper suggests that a reorganization of surface and deep-water circulations caused by the
opening of the Hispanic Corridor could have generated a mild cooling episode, finally affecting the survival of healdioid ostracods.Les modalités d’extinction de l’ostracofaune à la limite Pliensbachien-Toarcien sont discutées pour la coupe d’Almonacid de la Cuba
(Cordillère ibérique, NE Espagne), récemment proposée comme stratotype de limite complémentaire pour la limite Pliensbachien-Toarcien.
L’extinction la plus intense affectant l’ostracofaune ne se situe pas au sommet du Pliensbachien, mais près du sommet de la sous-zone à Mirabilis
(zone à Tenuicostatum). Les changements constatés au sein des associations d’ostracodes pourraient trouver leur origine dans la réorganisation de
la circulation océanique superficielle et thermohaline, résultant de l’ouverture du Corridor Hispanique. Cela aurait pour conséquence la mise en
place d’un épisode relativement froid, affectant finalement la survie des ostracodes healdioidés.</mods:abstract>
