When Portuguese priest Manuel Aires de Casal (1754\u20131821) found a gigantic bone from a prehistoric animal in the Northeast, he was astonished. He couldn\u2019t understand what type of animal could have possessed ribs \u201ca span and a half wide\u201d and tusks nearly a fathom long, or 6 feet (ft). In the book Corografia <\/em>bras\u00edlica <\/em>(Brazilian chorography), published in 1817, one of the first publications to record fossils in Brazil, he commented that \u201cit took all the strength of four men\u201d to collect the fascinating animal\u2019s lower jaw.<\/p>\n

Casal reports that he remembered hearing of the prehistoric mammoth fossils in North America, but he went on to conclude: \u201cPerhaps this quadruped is [the] Behemoth of which Job speaks in 40:10.\u201d Behemoth was the terrestrial equivalent of the mythological sea creature known as Leviathan, described as having a diet of oxen, \u201cbones like bronze pipes,\u201d and \u201ca skeleton like iron bars.\u201d The description made sense, because he assumed he was also describing an herbivorous animal that was large, heavy, and strong.<\/p>\n

In Europe, naturalists and philosophers have debated the possible origins of fossils from animals such as sharks and ammonites, an extinct group of mollusks. The discoveries fueled discussions about the diversity of life on Earth, which led to two hypotheses: major catastrophes could have wiped out ancient species, or animals were slowly replaced by their living relatives. English naturalist Charles Darwin (1809\u20131882) supported his theory of evolution with fossils found in South America; in Uruguay, he purchased a nearly complete fossil skull of a large mammal, later named Toxodon platensis<\/em>.<\/p>\n

In the eighteenth century, when Europe began recognizing the important role that fossils play in understanding the history of life on Earth, French naturalist Georges Cuvier (1769\u20131832) distinguished the remains of mastodons from those of elephants, but Casal ignored his arguments. According to paleontologist Antonio Carlos Sequeira Fernandes, of the National Museum at the Federal University of Rio de Janeiro (UFRJ), Casal\u2019s interpretations were dictated by his religious views, as he was a priest at the Santa Casa de Miseric\u00f3rdia Hospitals in Rio de Janeiro and in Crato, Cear\u00e1. \u201cThe bones that he described were from a mastodon skeleton,\u201d says Fernandes, who has been researching Brazil\u2019s paleontological history since the late 1990s.<\/p>\n

Closely related to mammoths, mastodons lived between 23 million and 11,700 years ago. They were 10 ft tall, with femurs 3 ft long and tusks averaging 4.6 ft. The jaws Casal described could have had up to thirty teeth, each 17 cm long. \u201cNot knowing what they really were, the first naturalists were quite surprised by the monstruous bones they found,\u201d admits Fernandes.<\/p>\n

In the eighteenth century, Casal was not the only one to confuse mastodons with monsters. One of the first records in Brazil of an animal from millions of years ago was made by Jo\u00e3o Batista de Azevedo Coutinho de Montaury (?\u20131810), governor of the capital of Cear\u00e1. In October 1784, he sent several boxes containing material of scientific interest by ship to the Portuguese minister Martinho de Melo e Castro (1716\u20131795). One of them contained \u201csix pieces of monstrous bones,\u201d as he described in the letter accompanying the package. Before loading the cargo, Montaury had been surprised by the bones\u2019 similarity to elephant skeletons from Africa, since there was no such \u201cmonstrous animal in this part of the Northeast, nor any evidence that there ever was one in this capital to which these bones could be attributed,\u201d he also wrote to his boss.<\/p>\n

Fernandes suspected that Montuary\u2019s bones were also from mastodons, but he was never able to confirm this: \u201cI looked at the Ajuda Museum and the Natural History Museum in Portugal, but nobody knew anything about them. They were likely lost.\u201d At least he found where the bones were presumably collected, based on information in the letter to Melo e Castro: a cavity in a rock on a farm in the present-day municipality of Sobral, in Cear\u00e1, as reported in a 2013 article in the journal Filosofia<\/em> e Hist\u00f3ria da Biologia<\/em> (Philosophy and history of biology).<\/p>\n

The First Collections<\/strong>
\nBack in the nineteenth century, in the municipality of Prados, in Minas Gerais, enslaved Afro-Brazilians came across a fossilized bone that they hit with a hoe while working in a mine. They thought it might be the remains of a tree. Until they found a tooth. The news reached Lu\u00eds da Cunha Meneses (1743\u20131819), governor of the capitals of Minas Gerais and Goi\u00e1s. In a letter to Melo e Castro, he noted: \u201cI don\u2019t think that such extraordinary news is negligible [\u00bc], so I immediately sent Sergeant Major Pires Sardinha to examine the state and quality of the so-called skeleton.\u201d<\/p>\n

Naturalist Sim\u00e3o Pires Sardinha (1751\u20131808) described what he called the \u201cmonstruous bone;\u201d since it was already decomposed, he could not identify the animal to which it belonged, but he also sent it to Lisbon. In Portugal, the material was studied by Italian physician and naturalist Domingos Vandelli (1735\u20131816), resulting in the first scientific article on Brazilian fossils, published in 1797 in Mem\u00f3rias da Academia Real das Sciencias de Lisboa<\/em> (Memoirs of the Lisbon Academy of Sciences).<\/p>\n

Over time, more precise explanations emerged. At the end of the eighteenth century, physician and botanist Manuel Arruda da C\u00e2mara (1752\u20131810) solved part of the mystery of the first fossils by assembling the first mastodon skeleton from what is now the state of Goi\u00e1s. The bones were collected during expeditions in the Northeast but were later sent to Portugal and lost.<\/p>\n

Remains from other animals have also been discovered. In the eighteenth century, Portuguese naturalist and military officer Jo\u00e3o da Silva Feij\u00f3 (1760\u20131824) was amazed by the fish fossils he found among the layers of yellowish rock at the bottom of an ancient lake in Cariri, in the Cear\u00e1 countryside, now recognized as one of the richest fossiliferous regions in the world. In September 1800, he wrote to Montaury: \u201cA collection of amphibian and fish fossils, the most curious and rare, in my opinion, that have ever been found.\u201d<\/p>\n

Feij\u00f3 was amazed by the exceptional condition of the soft tissues (organs, blood vessels, and muscles) of the \u201cimmense fish, completely transformed into crystal.\u201d Fossils from this region of Cear\u00e1 continue to be found with preserved tissues, feathers, and hair. \u201cToday, 200 years later, we are still studying how fossils preserve their soft tissues,\u201d says paleontologist Ismar de Souza Carvalho, of UFRJ.<\/p>\n

Feij\u00f3 was one of the first to amass a scientific collection of fossils at the Royal Academy of Engineering, in Rio de Janeiro. Naturalists like Frederico Leopoldo Cezar Burlamaqui (1803\u20131866) from Piau\u00ed also assembled their collections. He collected vertebrate and invertebrate fossils for the newly founded Royal Museum (called the National Museum from 1890 onwards), of which he was director from 1847 to 1866. The collection included bird eggs from islands in Peru, fish from Crato, and bones.<\/p>\n

Burlamaqui collected some fossils himself. Others he acquired through donations, such as the femur of a megatherium, a group of sloths about 12 ft tall with strong jaws and long claws that lived throughout South America between 35 million and 12,000 years ago.<\/p>\n

With the collection in hand, Burlamaqui dedicated himself to analysis and, in 1855, published the first article on paleontology in a Brazilian scientific journal, Trabalhos da Sociedade Vellosiana<\/em>. However, many of the labels and descriptions for fossils in his collection have been lost due to poor infrastructure in the early years of the museum and changes in its location. \u201cA large number of fossils, especially megafauna, have no information about their origin,\u201d Fernandes explains.<\/p>\n

The records contained in the collection created by American zoologist and paleontologist Edward Drinker Cope (1840\u20131897) are better preserved. After graduating from the University of Pennsylvania in 1861, Cope worked with reptile fossils from North and Central America. One of his colleagues, American geologist Orville Adalbert Derby (1851\u20131915), who worked in Brazil, collected fossils in Pernambuco, Sergipe, Bahia, and S\u00e3o Paulo and sent what he found to Cope for analysis in the United States, where the materials collected in Brazil by British geologist Samuel Allport (1816\u20131887) were also sent. \u201cIn just one article from 1886, Cope described five fish, two reptiles, and one mammal from fossils found in Bahia, Pernambuco, Sergipe, and S\u00e3o Paulo,\u201d says paleontologist Val\u00e9ria Gallo, of Rio de Janeiro State University (UERJ), who studied the so-called Cope Collection at the National Museum.<\/p>\n

One of the animals described by the American was the mesosaur Stereosternum tumidum<\/em>, a marine reptile that lived between 286 million and 258 million years ago. Found on the coasts of South Africa and South America, this group\u2019s fossils confirmed the continental drift theory, proposed in 1912 by German Alfred Wegener (1880\u20131930). About 80 centimeters (cm) long, with thin conical teeth and a long tail with up to 64 vertebrae, S. tumidum <\/em>has been found in sedimentary basins in Paran\u00e1 and South Africa, indicating that the two continents were once united.<\/p>\n

Cope also described the crocodile Hyposaurus derbianus<\/em>. Found in the Northeast, this species\u2019 fossils have a long, triangular jaw and teeth that measure almost 3 cm long. They must have lived between 65 million and 55 million years ago.<\/p>\n

The fossils from the National Museum that Cope studied were sold to American geologist Henry Fairfield Osborn (1857\u20131935), who deposited them in the American Museum of Natural History, in Washington. They were then sent to the British paleontologist Arthur Woodward (1864\u20131944). Decades later, at the behest of Brazilian Llewellyn Ivor Price (1905\u20131980), some of this material was returned to Brazil and remained at the National Museum until it was destroyed in a fire in 2018.<\/p>\n

An important name in nineteenth-century Brazilian paleontology and archaeology was Dane Peter Wilhelm Lund (1801\u20131880). He worked and died in the region of Lagoa Santa, Minas Gerais. \u201cOn his expeditions, Lund collected over 10,000 fossils, mostly of megafauna from the current period, the Quaternary [which began 2.58 million years ago], such as saber-toothed tigers, giant sloths, and horses,\u201d Carvalho says.<\/p>\n

Lund\u2019s tigers were from the Smilodon populator<\/em> species, estimated to be 10 ft long, weighing 900 pounds, with sharp, curved, and serrated canine teeth up to 30 cm long. The tiger lived throughout the Americas between 700,000 and 11 million years ago\u2014in Brazil, in the present-day states of Cear\u00e1, Sergipe, Mato Grosso do Sul, Bahia, and Minas Gerais. Lund described the cat\u2019s complete skull, whose two canines and incisors (other front teeth) were preserved. Most of what he collected in Brazil is at the Copenhagen Zoological Museum in Denmark.<\/p>\n

\u201cThe first collections, like Lund\u2019s, still serve as a reference for those who want detailed accounts of the species that lived in Brazil thousands or millions of years ago,\u201d says UERJ paleontologist Herm\u00ednio Ismael de Ara\u00fajo J\u00fanior, president of the Brazilian Paleontology Society (SBP). The first discoveries also indicate the location of paleontological sites, and they are valuable for tourism.<\/p>\n

Since Montaury, naturalists and paleontologists have identified hundreds of species of Brazilian fossils\u2014at least 55 dinosaurs alone. Every year, more animals are discovered and published, such as the titanosaur Tiamat valdecii <\/em>(see <\/em>Pesquisa FAPESP issue n\u00b0 341<\/em><\/a>) and the crocodile Caipirasuchus catanduvensis<\/em>, both described in 2024.<\/p>\n

A large part of the fossil collection was lost in the fire at the National Museum, but there are other important collections at institutions such as the universities of S\u00e3o Paulo (USP), Rio de Janeiro (UFRJ), Rio Grande do Norte (UFRN), Pernambuco (UFPE), and Rio Grande do Sul (UFRGS), the Pontifical Catholic University (PUC) of Minas Gerais and the Museum of Earth Sciences in Rio de Janeiro.<\/p>\n
