An ornithopod dinosaur postcranial skeleton from the 
Early Cretaceous of Galve (Teruel province,Spain), 
assigned to Iguanodon bernissartensis by the French 
paleontologist Albert de Lapparent in 1960, is 
redescribed. It comes from La Maca 3 locality, early 
Barremian in age (Camarillas Formation) and it is made of 
several cervical vertebrae, fragmentary remains of the 
dorsal and sacral series, several caudal vertebrae, 
fragments of cervical, dorsal and sternal ribs, fragments 
of chevrons and ossified tendons, and an incomplete left 
hip. It has been identified as an «iguanodontid» (i.e., a 
non-hadrosaurid iguanodontoid) by the presence of a deep 
prepubic blade and the absence of antitrochanter on 
ilium. The skeleton represents a new iguanodontoid taxon, 
Delapparentia turolensis nov. gen et sp., characterized 
by the following autapomorphies: 1) posterior dorsal ribs 
with long, parallel and unfused capitulum and tuberculum, 
2) ossified sternal ribs, and 3) straight and 
lateromedially expanded preacetabular process of ilium 
(convergent in Zalmoxes). It also presents a combination 
of anterior dorsal ribs with a pneumatic foramen, and a 
ischium of big size in relation to ilium.

A Spanish news article with a reconstruction also 
discusses the find:

The dinosaur (nicknamed "el macasaurio") was more than 10
