Perché le vertebre dorsali di Spinosaurus hanno lunghezza comparabili a quelle dei grandi tyrannosauridi e carcharodontosauridi, mentre le faccette articolari e gli archi neurali sono marcatamente più piccoli? Come spiegare questa anomalia? Nell'istituire Sigilmassasaurus, Russell (1996) incluse tra il materiale riferibile a questo taxon varie vertebre dorsali isolate, appartenenti ad

Nel precedente post, ho discusso le affinità di due omeri parziali dal Cenomaniano del Marocco. Un omero distale mostra caratteri in comune con Baryonyx e può essere riferito a Spinosaurus, come già ipotizzato da Russell (1996). Usando l'olotipo di Baryonyx come riferimento, l'esemplare marocchino risulta ampio circa 85% del theropode inglese. Il tema principale del post era comunque un altro

Questo post vuole rimediare ad un altro post scritto anni fa, quando il blog era giovane. Mea Culpa! In quel post, accennai ad un omero parziale di dinosauro descritto brevemente da Russell (1996) e proveniente dal Cenomaniano del Marocco. Nel mio post di quei tempi giovanili, ipotizzai chequell'omero potesse appartenere a Spinosaurus, e completai leparti mancanti usando Baryonyx come

Spinosaurus (ed il suo potenziale sinonimo Sigilmassasaurus), Carcharodontosaurus, Deltadromeus (ed il suo potenziale sinonimo – per ora solo egiziano – Bahariasaurus), Sauroniops, sono tutti taxa con dimensioni adulte che si attestano nella categoria dei mega-theropodi.
