DescriptionNasutoceratopsini de Aldama Chihuahua.jpg |
Español: Cráneo de un Nasutoceratopsini no descrito y sin nombrar exhibido en el Museo del Mamuth en la ciudad de Chihuahua, proveniente del municipio de Aldama. Aunque no ha sido descrito formalmente ni de forma adecuada se ha hecho mención de los restos fósiles en tres artículos Ramírez-Velasco & Hernández-Rivera 2015a y b, y "Rivera-Sylva y Carpenter 2014b:
"hay algunos ejemplares que presentan rasgos semejantes al centrosaurino Nasutoceratops de Utah (RAMÍREZ-VELASCO y HERNANDEZ-RIVERA, 2015). Si así fuera, esto representaría una nueva especie y, por la edad, una de las más antiguas de Norteamérica" [1] "Rivera-Sylva y Carpenter (2014b) mencionan dos esqueletos de chasmosaurinos exhibidos en el Museo del Mamut de Chihuahua. Uno de ellos presenta rasgos craneales semejantes a Nasutoceratops (Sampson et al., 2014), por lo que se le considera como probable centrosaurino." [2]References
