Masiakasaurus

Description

Masiakasaurus (signifiant « lézard violent », du malgache masiaka) est un genre éteint de dinosaures théropodes de la famille des Noasauridae ayant vécu à Madagascar à la fin du Crétacé supérieur, au Maastrichtien, il y a environ entre 72 et 66 Ma (millions d'années).
Une seule espèce est connue, l'espèce type : Masiakasaurus knopfleri, nommée d'après le fondateur du groupe Dire Straits, Mark Knopfler, à qui, les chercheurs, Sampson et son équipe, attribuent l'inspiration de leur expédition.
