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

Talita the Tapejara. She is first gen and loves Brazil but sadly has never been there. She speaks broken Brazilian Portuguese. She is pretty small, ony 4'10 or 147cm. Very hyperactive but sleeps like a rock.
