Cariocecus

Naam beteken: “named after the Iberian war god Cariocecus”1

Het geëet: PlantePlantvreters met snawelsVroeë Kryt

Cariocecus was a medium-sized plant-eating dinosaur that lived in what is now Portugal. It had a bony brow over its eye that made it look like an eagle, and its upper jaw bones were fused together to help it chew tough plants.1

Prettige feite

Cariocecus is the first iguanodontian skull ever found in Portugal.1

The skull of Cariocecus was about 45 centimetres (18 inches) long, and the animal was not fully grown when it died.2

Its maxilla and jugal bones were completely fused together, which is unique among all ornithopods.1

Cariocecus had a large bony brow over its eye that may have protected it from sun glare and injury.1

Scientists used micro-CT scanning to study the inside of the skull, including the brain and inner ear.2

Cariocecus lived alongside the spinosaurid Iberospinus and other dinosaurs in a shallow coastal environment.1

The fossil was discovered in 2016 by Pedro Marrecas and was named in 2025.1

KI-prent van Cariocecus — 'n KI-prent van hoe Cariocecus dalk gelyk het, deur 'n rekenaar gemaak uit wat wetenskaplikes weet. Dit is 'n raaiskoot: die regte dier het dalk anders gelyk, en niemand weet wat sy regte kleure was nie.

Vir dino-kenners

Wetenskaplike naam: Cariocecus
Benoem deur: Bertozzo et al. 20254
Groep: Plantvreters met snawels
Familie / klade: Hadrosauroidea4
Klassifikasie: Ornithischia > Ornithopoda > Iguanodontia4
Ouderdom van die rotse: 126 tot 121 miljoen jaar (Barremian)4
Rotsformasies: Papo Seco4
Lande: Portugal4
Fossielrekords: 1 in The Paleobiology Database4
Ontdekking: The only known skull was found in 2016 by Pedro Marrecas in a limestone outcrop in Portugal. It was named Cariocecus bocagei in 2025 by Filippo Bertozzo and colleagues.1
Steeds omstrede: Scientists are not sure exactly how large Cariocecus grew, because the only known fossil is from a young individual.1
