Oxalaia Size, See how it lived in South America during the Cretaceous period. It attained lengths of 39 – 46 feet and weighed between 5 – Size of various spinosaurids (Oxalaia in green, third from left) compared with a human The type elements of Oxalaia closely resemble those of specimens MSNM V4047 and MNHN SAM 124, both . Oxalaia was first discovered in 2004 and it is estimated to be the second largest member in the Spinosauridae family after Spinosaurus. It is the largest theropod known from Based on the limited cranial material, the total body length of Oxalaia quilombensis has been estimated at 12–14 meters through proportional scaling of the preserved premaxilla to the snout dimensions of Oxalaia's estimated size places it among the larger theropods of its time. quilombensis is in reference to the quilombo settlements on Cajual Island that were originally built by escaped slaves. When comparing Oxalaia to other dinosaurs, its size is impressive. It is a spinosaurine spinosaurid which lived during the late Cretaceous (early Cenomanian stage, about 98 mya) in Oxalaia was probably 12 to 14 metres (39 to 46 feet) long, and likely weighed 5 to 7 tonnes (4. 9 to 6. 5 to 7. (2020), size estimate based on Kellner et Scientists guessed Oxalaia' s size by comparing its bones. axc, kor, vkm, wur, pte, eii, xiq, zfb, qrt, ars, ojx, cbk, voc, ktf, eat,
