El Tio🇧🇴 Based on two large Megaraptoran footprints from the El Molino Formation Based on a video from Vividen: Paleontology Evolved Estimated being 12.3 meters long and weighing 10 tons? Originally thought to be Sauropod tracks in a 2021 paper Hopefully they find actual fossils of this thing one day

Not completely sure how they came to the conclusion that the footprints came from a Megaraptoran tho. But then again it makes sense since the El Molino formation dates back to the Maastrichtian stage of the Cretaceous and at that time Abelisaurids and Megaraptorans filled in the Apex predator niches once the Carcharodontosaurs went extinct tens of millions of years earlier. I tried to find the 2021 paper but it's a no go. But I did find a reddit post (No I don't use reddit) where it goes by another name called "Vasiliasaurus maximus" or the Largest Royal Lizard. The comments are full of people arguing on whether or not El Tio was an Abelisaur or Megaraptoran and referencing to the Titanovenator abelisaur of Late Cretaceous Kenya. I do sincerely hope paleontologists down in Bolivia try their hardest to find actual megaraptoran fossils soon. They were more diverse than we realized especially in South America, so I don't think a T.rex sized Megaraptor isn't out the realm of possibility.

Some indeterminate theropods from Brazil🇧🇷 Some unknown Megaraptorans and Carcharodontosaurs. There's very limited fossil material from these guys so take all of their interpretations with a wheelbarrow of salt. Check the Alts for more details.

Araripevenator martinensis. SMNS 58023 Based on an April 2018 paper Comes from the Romauldo Formation Consists of a partial sacrum + two anterior caudal vertebrae + an illium From the Albian Stage of the Early Cretaceous Roughly the same size as Fukuiraptor or a bit bigger Full size possibly 4.9 meters long and weighing up to 590kg Apparently it was stolen from Brazil and therefore must be repatriated Indeterminate Carcharodontosaur Specimen NHM PV R.2129(b) or "Gomez" as some researchers call it Also called "Brazilian Titan" by others on Twitter Based on an April 2024 paper by Kamila L. N. Bandeira Only known from a middle caudal centrum or tail vertebra From the Recônavo Basin Marfim Formation in the Bahia state Inspired by videos from Vividen: Paleontology Evolved Latest Calculations put its full size at 16.8 meters long and 20.86 tons Disturbingly large for a theropod, more conversative estimates should be considered. Color scheme based on the Hemprich's Coral Snake, native to Brazil From the Valanginian-Hauterivian stage of the Early Cretaceous Indeterminate Megaraptoran Specimen MPMA-08-003-94 or "Giant Brazilian Megaraptoran" Only known from a large caudal vertebra From the São José do Rio Preto Formation of the Bauru group of the Paraná Basin Likely rivaled Maip in size being in the 8-10 meter range and weighed 1-3 tons. From the Coniacian-Maastrichtian Stage of the Late Cretaceous Megaraptorans got to their largest sizes in Late Cretaceous South America Color scheme based off Brazilian Coral Snake, native to Brazil (obviously) Indeterminate Carcharodontosaur From the Alcântara Formation Laje do Coringa of Cajual Island Only known from a few maxillary and dentary teeth Based off Carcharodontosaurus specimen UCRC PV12 Specimen referenced and described in Nizar Ibrahim paper 2020 Estimated size is at 11 meters and weight being 7 tons at best From the Cenomanian stage of the Late Cretaceous
