1. Crocodiles are normally solitary, although hatchlings tend to stay together and some species will continue to live in family groups. Today, Giganotosaurus is believed to have been slightly larger than T. rex, though even Giganotosaurus ranks behind Spinosaurus in size among the meat-eating dinosaurs. It also had something the Spinosaurus did not have, a long, heavy tail which balanced out its enormous head and torso. Fossils of Mapusaurus, a relative of Giganotosaurus, have been found grouped closely together. Mapusaurus rosae, was a 9-10 metre long Carcharodontosaurid living in what is now present day Argentinian Patagonia, South America. Acrocanthosaurus also lived during the same time as the three other carcharodontosaurids, and is a carcharodontosaurid itself, so I decided to count its teeth as well. Despite their aggressive nature, Majungasaurus are one of the easier carnivorous dinosaurs to keep due to their relatively low comfort threshold. Yes they did, along with a number of other large theropods. Brusatte et al., (2010) (Figures 1-2; Table 2): https://pdfs.semanticscholar.org/4069/64fde0143305ce9218d4cbab4c6a54bc3a8c.pdf, https://images.app.goo.gl/3if11LqhaCVRhYkeA. Carcharodontosaurus also had 10 denticles per 5 mm on its teeth (measured on 11/9/20 in Sereno et al., 1996, pg. MUCPv-CH 1's Maxilla (Canale et al., 2014, Figure 3): hin that is “V-shaped,” and there is a groove on the body of the dentaries, (Coria and Salgado, 1995, pg. See more ideas about Dinosaur, Prehistoric animals, Prehistoric. Mapusaurus roseae Mapusaurus ("Earth lizard") was a giant carnosaurian, Carcharodontosaurid dinosaur from the early Late Cretaceous (late Cenomanian to early Turonian stage) of what is now Argentina and possibly Chile. 225 Figure 1 "A"). (Cenomanian): http://fossilworks.org/?a=taxonInfo&taxon_no=276460, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4579021/figure/fig-2/. Mapusaurus. Taller and longer but slimmer than Tyrannosaurus rex, Giganotosaurus lived millions of years earlier and in South America not North America. I learned about Giganotosaurus first from Chased by Dinosaurs, and then Mapusaurus from Horizon: "Extreme Dinosaurs" and Dinosaurs: Giants of Patagonia.For a long time, I've thought that Giganotosaurus was larger than Mapusaurus, and that both of them lived at the same time. Mapusaurus was excavated between 1997 and 2001, by the Argentinian-Canadian Dinosaur Project, from an exposure of the Huincul Formation (Rio Limay Subgroup, Cenomanian) at Cañadón del Gato.It was described and named by paleontologists Rodolfo Coria and Phil Currie in 2006. Here is a comparison:But even Spinosaurus was dwarfed by some of the long-necked herbivorous sauropods, such as Diplodocus, which are the largest dinosaurs known to have existed. Stromer (1931) backs this up by saying that the holotype of Carcharodontosaurus had, "18-20 serrations on a 1 cm length of margin,". Being this size, it was the alpha predator of its region. However, they didn't point out the second one. Paleontologist Rodolfo Coria, of the Museo Carmen Funes, contrary to his published article, repeated in a press-conference earlier suggestions that this congregation of fossil bones may indicate that Mapusaurus hunted in groups and worked together to take down large prey, such as the immense sauropod Argentinosaurus. But studies prove that Mapusaurus is a slightly different dinosaur, with a smaller, lighter build, weaker jaws, more of a pack hunter, and a slightly larger brain. 83 Figure 7):

Giganotosaurus is often thought to be a pack hunter, since numerous skeletons have been found together in massive bone beds. The new species was named Mapusaurus after the word for "Earth" in the language of the Mapuches, the tribe that lives in the area. Currie and Carpenter (1999) (Pg. Giganotosaurus lived around 100 million years ago while Argentinosaurus lived around 95-94 million years ago. A titanosaur caudal vertebra was discovered there that has been attributed to Andesaurus, "Edad de la Formacion Bajo Barreal," pg. Carr et al., (2017) (“Discussion: Ontogenetic tooth count reduction” p. 1-2): https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5372470/, http://www.app.pan.pl/archive/published/app48/app48-161.pdf, https://zookeys.pensoft.net/article/47517/zoom/fig/1139/, https://zookeys.pensoft.net/article/47517/. Universidad Autonoma de Madrid. There are 8-9 denticles per 5 mm for Mapusaurus compared to 8-10 denticles per 5 mm in Giganotosaurus (Canale et al., 2014, pg. Tyrannosaurus also has the advantage of having multiple good specimens, whereas Giganotosaurus has one, Mapusaurus has a big bonebed, and Carcharodontosaurus doesn't really have any (the best specimens of it are still woefully incomplete). The holotype specimen's (MUCPv-Ch1) skeleton was about 70% complete and included the skull, pelvis, leg bones and most of the backbone. 7-8, "Description: Teeth: Denticles"): Young et al., (2014) ("Abstract," "Introduction" p. 2): Just in case, I decided to count the teeth in two other theropods. They also have up to 12 serrations per 5 mm maximum on their teeth. I originally thought of that back in 2016 (I think), but now the question has seeped back into my mind. 225 Figure "C"). 83 Figure 7): The biggest difference might be the two genera's skull designs. Fossilworks. - Duration: 2:16. I learned about Giganotosaurus first from, larger than Giganotosaurus (12.4-13.1 meters). The authors stated that they couldn't. Share your thoughts, experiences and the tales behind the art. Some people says that this time difference is enough to say they were different.It certainly is, but what we don't know exactly is when the species appeared. Henderson (2018) ("Materials and Methods" p. 2, Figure 1 and 5, Table 1-2): (“Discussion: Ontogenetic tooth count reduction” p. 1-2): As for Giganotosaurus' and Mapusaurus' post-cranial skeletons: Mapusaurus Scapula (Coria and Currie, 2006, Figure 19): (Mapusaurus’ femur head appears to be incomplete, as shown in Coria and Curre, 2006, pg. A single Mapusaurus might have bagged a juvenile, but “you would need a pack of them to take down an adult Argentinasaurus”, says Tom Holtz at the University of Maryland in College Park, US. Parasaurolophus 67 9,475 views. The authors noted that the structure of the femur suggests a closer relationship with Giganotosaurus than either taxon shares with Carcharodontosaurus. 101 Figure 28 "B"-"C").

It was roughly similar in size to its close relative Giganotosaurus, averaging about 12.4 meters and 7 tonnes and getting to 13.6 meters long and 8.5 … Since Carcharodontosaurus is related to both Giganotosaurus and Mapusaurus, and lived during the same time but lived in Africa, I wanted to see if it had the same number of teeth. As I've explained before, I've read that Giganotosaurus lived before Mapusaurus. Even at this reduced estimate, the predator was still obviously a very lar… Going back to assemble of Giganotosaurus dino robot, you can first choose to assembled form: dinosaur robot assembly or a transform robot assembly. 5 Figure 4 "C"): Merriam Webster. It seems that Tyrannotitan had 15 teeth in its dentary, just like Giganotosaurus and Mapusaurus did. Giganotosaurus had 3 fingers on its hands, not 2 like T.rex. Mapusaurus is about the size of T-Rex and Allosaurus, at around 40-42 feet long. PPBA Mapusaurus vs Giganotosaurus remake - Duration: 0:34. 1,583 Pages. I tried to look for the Mapusaurus' pneumatic foramen in Coria and Currie (2006) (pg. Popular Categories. The fact that they had died together is a good indication that they had been living together up to the time of their death, and the interesting thing is that is suggests very strongly that Mapusaurus was a packing animal like some tyrannosaurs. 101). "Fraxinoipollenites fragilis." Giganotosaurus is known from very fragmentary remains. A couple of papers, and a book, have proposed that Suchomimus, 22 maxilla teeth (1 and 3 are missing for Baryonyx) (, . It was the largest terrestrial carnivores to ever live, even larger than Tyrannosaurus rex. This is 3 denticles greater than both Giganotosaurus and Mapusaurus, and 5 greater than Carcharodontosaurus. 4. Deak and McKenzie (2016) ("Conclusions"): https://www.researchgate.net/publication/309340780_HYPOTHETICAL_DIVERGENT_EVOLUTION_OF_TWO_APEX_PREDATORS_FROM_THE_HELL_CREEK_FORMATION_NANOTYRANNUS_LANCENSIS_AND_TYRANNOSAURUS_REXLink 2:https://slideplayer.com/slide/12062708/, https://www.app.pan.pl/archive/published/app48/app48-191.pdf. Oddly enough, the (? (Albian-Coniacian): http://fossilworks.org/bridge.pl?a=taxonInfo&taxon_no=276456Equisetosporites cf. Interestingly, Coria and Salgado (1995) originally showed Giganotosaurus' ilium to look more like Acrocanthosaurus' (pg. A normal adult is larger than that of a Tyrannosaurus. For example "Mapusaurus" was a close relative of "Giganotosaurus", and the data on this animal is not fully complete. A second specimen (MUCPv-95), 8% larger, has also been recovered. 988 Figure 2 "A"): It looks like Carcharodontosaurus has four teeth in both premaxilla like Giganotosaurus and Mapusaurus, but 14 teeth in its maxilla. (Albian-Cenomanian): http://fossilworks.org/bridge.pl?a=taxonInfo&taxon_no=276463, Laboratory of Paleobotany. The type genus was Carcharodontosaurus, a huge Carcharodontosaur from Africa. If Mapusaurus was the top predator of its ecosystem (that means, it could be hunted only by other Mapusaurus), tha absence of other predators in the site is clearly explained. 57, Now we have to tackle the second, and main, question of this post: Where Giganotosaurus and Mapusaurus the same genus? 7-8, "Description: Teeth: Denticles"). In order to figure out when these two animals lived, we need to talk about the formations where they were discovered. According to modern size estimates, Spinosaurus was the longest known theropod dinosaur of all time, even longer than Mapusaurus, Tyrannosaurus, Giganotosaurus and Carcharodontosaurus.
