Yag??e, P., Dantas, P., Ortega, E, Cachão, M., Santos,E A. M.,Goncalves,R. i Lopes, S. (2006) opisali nowego zauropoda z g??rnej jury z Lourinhã w Portugalii. Nowoopisany zauropod zosta?? odkryty w g??rnych piaskowcach formacji Bombarral z grupy Lourinhã (g??rna jura, tyton, oko??o 150-145 MLT). Zosta??y odkryte w miarÄ? dobrze zachowane krÄ?gi ogonowe zwierzÄ?cia.
Ca??o??Ă„? - po angielsku: pisze:Yag??e, P., Dantas, P., Ortega, E, Cachão, M., Santos,E A. M.,Goncalves,R.& Lopes, S.(2006 New sauropod material from the Upper Jurassic of Areia Branca (Lourinhã, Portugal). - N. Jb. Geol. Pal?¤ont. Abh., 240: 313-342; Stuttgart.

Abstract: We report new sauropod material from the upper sandstones of the Bombarral Formation of the Lourinhã Group (Upper Jurassic, Tithonian) at the Praia da Areia Branca cliffs (Lourinhã region, west coast of Portugal). The new specimen is represented by an articulated, well-preserved, partial tail of an animal of an estimated length of 22 m. The specimen was recovered from beds related to a fluvial/upper delta plain environment of a deltaic system.

Currently, nine caudal vertebrae and four chevrons have been prepared. The specimen bears some tooth marks that are attributed to a large theropod. All the recovered bones are articulated, suggesting that an almost complete individual is most probably preserved in the lower layer of the bottom of the cliff. A geophysical test was performed to test this hypothesis. These analyses are not completely conclusive but the presence of resistive anomalies is discussed.
