Abstract
El estudio de la osteohistología en dinosaurios permite evaluar patrones de crecimiento y su relación con cambios biomecánicos. En este trabajo se analiza una tibia asignada a un iguanodontio indeterminado del yacimiento Masía de los Cerezos (Formación El Castellar, Cretácico Inferior, Teruel). La sección histológica revela una estructura cortical compleja, caracterizada por una distribución vascular asimétrica, un engrosamiento cortical anterolateral y la presencia de tejido esponjoso grueso compactado. Esta microanatomía sugiere una redistribución de cargas, posiblemente asociada a un cambio postural previo a la madurez esquelética. Los resultados destacan la importancia del estudio osteohistológico en Iguanodontia para comprender la relación entre ontogenia y locomoción, y subrayan la necesidad de ampliar el análisis a más taxones y estados ontogenéticos para evaluar la variabilidad microanatómica dentro de este grupo.

The study of osteohistology in dinosaurs allows us to evaluate growth patterns and their relationship with biomechanical changes. In this paper we analyse a tibia assigned to an undetermined iguanodontid from the Masía de los Cerezos site (El Castellar Formation, Lower Cretaceous, Teruel). The histological section reveals a complex cortical structure, characterised by an asymmetric vascular distribution, anterolateral cortical thickening and the presence of compacted coarse cancellous tissue. This microanatomy suggests a redistribution of loads, possibly associated with a postural change prior to skeletal maturity. The results highlight the importance of the osteohistological study in Iguanodontia to understand the relationship between ontogeny and locomotion, and underline the need to extend the analysis to more taxa and ontogenetic stages to assess microanatomical variability within this group.
