Abstract
A single brachiosaurid sauropod cervical vertebra from
the Wessex Formation (Barremian, Early Cretaceous) of
the Isle of Wight is remarkable for its size. With a
partial centrum length (i.e., excluding evidence of
the anterior condyle) of 745 mm it represents the
largest sauropod cervical reported from Europe and is
close in size to cervical vertebrae of the giant
brachiosaurid Brachiosaurus brancai from Late Jurassic
Tanzania. The complete animal probably exceeded 20 m
in total length. The specimen shares important
morphological characters with Sauroposeidon proteles
from Early Cretaceous USA, including extensive lateral
fossae and well-developed posterior
centroparapophyseal laminae, indicating that it is
part of a Brachiosaurus?Sauroposeidon clade, and in
some characters is intermediate between the two. Owing
to the complexities of Isle of Wight sauropod taxonomy
the specimen is not attributed to a named taxon.
