Ankylosaurus magniventris

Ankylosaurus magniventris est species dinosauriorum armatorum. Eius fossilia in formationibus geologicis ex Cretaceo exeunte, abhinc annorum a 68 ad 66 milliones fere inventa sunt, in America Septentrionali occidentali, ut inter ultima ex dinosauriis non avianis sit. Binomen a Barnum Brown anno 1908 erectum est, sola species generis Ankylosauri. Nomen generis 'lacertam fusam', speciei 'ventrem magnum' significat. Aliquot specimina excavata sunt, sed sceletus plenus non dum inventus est. Quamquam aliae ankylosauridae a plenioribus fossilibus repraesentantur, haec species archetypus omnis gregis saepe habetur, contra nonnullas proprietates inusitatas.

Calvaria holotypi AMNH 5895 et diagramma refectum.

Magnitudines minimi (AMNH 5214) et maximi (CMN 8880) speciminum descriptorum, cum homine comparatorum.

Sceletus anno 1908 compositus (AMNH 5895), partibus carentibus ex Stegosauro hypothetice refectis.

Excavatio speciminis AMNH 5214 (media parte imaginis), 1910.

Ankylosaurus magniventris, fortasse maxima ex ankylosauridis, a 6 ad 8 metra longus, et a 4.8 ad 8 tonnas metricas ponderis fuisse aestimatur. Quadrupedalis erat, corpore lato et robusto, cui erat calvaria humilis et lata, binis cornibus retro a tergo capitis, binisque cornibus infra retro et deorsum monstrantibus. Eius nares, aliorum ankylosauriorum dissimiles, in obliquum, non prorsum, monstrabant. Anterior maxillarum pars rostro tegebatur, cum seriebus parvorum dentium foliformium. Osteodermis, laminis armatis, tegebatur, demi-anulis osseis collum tegentibus. Cauda finem in magna clava capiebat. Ossa in calvaria aliisque corporis partibus coalescebant, vires augentia, et haec proprietas est origo nominis generici.

Ankylosaurus est genus familiae Ankylosauridarum, et eius cognata proxima Anodontosaurus et Euoplocephalus videntur.
