Fossils are the remains or traces of living beings that lived in the past, throughout the history of life on Earth, which are preserved in rocks in the form of shells, bones, teeth, impressions, eggs, petrified feces, tracks and footprints.
The Earth Sciences Museum has a collection of minerals, the number of which make it the second or third collection of minerals in Brazil, and a large amount of fossils that allows us to say that we have the first, second and third collections. of fossils in the country.
AgateEARTH SCIENCE MUSEUM
The Earth Sciences Museum, from the Geological Service of Brazil, houses the most important collection of the country's geological and paleontological heritage, acquiring, keeping, preserving and disseminating beautiful samples of minerals, rocks and meteorites.

The Earth Sciences Museum has a valuable documentary and iconographic collection, and instruments such as microscopes, magnifying glasses, compasses and theodolites.
These samples, collected in the most diverse points of the national territory, include hundreds of specimens that were recognized and classified, for the first time, in Brazil. In addition to these Brazilian specimens, it also has other materials of foreign origin, including about 60 meteorites, which were acquired, in large part, through barter.
Dolores IglesiasEARTH SCIENCE MUSEUM
The Museum also conserves an enormous amount of historical documents related to the development of the country's geological knowledge, such as maps, field notebooks, photos, manuscripts and notes, prepared by the pioneers of Brazilian geology and paleontology.
The Museum of Earth Sciences has a library with more than 90,000 volumes, mainly dedicated to the areas of petrology, mineralogy and paleontology, as well as collections of periodicals from various geological services around the world. This library was carefully organized under the aegis of Dolores Iglesias and Maria da Glória Tavares Price.
These collections result from the work carried out by several generations of geoscientists and collaborators who passed through the Geological Mineralogical Service of Brazil (1907-1934), the National Department of Mineral Production (1934-2017) and the Geological Service of Brazil itself - CPRM (1969)
This entire set characterizes the Museum as the most complete and representative collection of geological research and mineral prospecting activities carried out in Brazilian territory.

This collection of minerals and rocks is considered one of the most important in the country, both in terms of the number of copies and the quality of the items in the collection.
The rocks that are in furniture that spreads along the walls of the minerals hall are classified as igneous or magmatic, metamorphic, sedimentary (including pyroclastic) rocks, industrial rocks, rocks from the state of Rio de Janeiro and, to complete this exposition two cabinets with the meteorites from the collection, in the westernmost part of the hall.
The petrographic exhibition is organized in such a way as to allow the visitor to understand that rocks are aggregates of minerals and that their most used classification is based on their genesis, but also on the size of the grains and on their texture and distribution in the rock. In one of its showcases, the main minerals that constitute a rock are presented – in this case, a granite with its minerals – quartz, feldspar and mica.

The fossils are presented in two different shows. The first – in the Time of Dinosaurs – where pieces from the Museum’s collection are organized in a way that seeks to serve the young audience, richly illustrated and with mounted reptile skeletons.

The other exhibit – Giants and Miniatures – presents the real bones of Quaternary mammals, the so-called megafauna, compared with microfossils that can only be properly observed under a microscope.
The paleontological exhibition, called In the time of the dinosaurs, focuses on aspects of a brief moment in the history of life, the Mesozoic era in the territory we now call Brazil. It is the story of a very different world, where the seas were populated by the ammonites and by large marine lizards, the mosasaurs. The continents were united and many areas that today are many meters above sea level were submerged.

Later, flying reptiles appeared – the pterosaurs – such as Anhanguera and Tupandactylus which, with their five-meter wingspan, flew over the region that is now the Brazilian Northeast. The continents split.

On land, the dominance of large reptiles was established, among which the crocodilians (Baurusuchus), the Cretaceous titanosaurs of the Triângulo Mineiro and the Angaturama, a large carnivore from the Chapada do Araripe, stood out.
From the Triângulo Mineiro, it is worth mentioning the exceptional occurrence of 4 fossil eggs, both herbivorous and carnivorous dinosaurs.
Also noteworthy are the examples of plants from the Cretaceous of Araripe that already show the first angiosperms, the flowering plants, to appear on the planet. Along with plants appear arthropods, represented by crustaceans (shrimps), insects (dragonflies) and arachnids. 65 million years ago, new animals and plants appeared on the earth's surface that replaced most of the existing forms, giving way to the radiation of birds and mammals.
Attached hall that houses Price's exhibitionEARTH SCIENCE MUSEUM
The exhibition in honor of the paleontologist Llewellyn Ivor Price (1905-1980), which presents his work room and allows for an understanding, through the display of the instruments, he used
his method of work in collecting, preparing, illustrating and studying the numerous fossils he described, serves as an example of the research carried out by his colleagues in the Paleontology Section of the former Division of Geology and Mineralogy
of which stand out Paulo Erichsen de Oliveira (1911-1969), Friedrich Wilhelm Sommer (1907-1994), Elias Dolianiti (1911-1985) and Rubens da Silva Santos (1918-1996).
This entire collection has a dual function. To allow scientific proof of the facts presented in articles and reports, as well as to raise awareness among those who are reached by the dissemination, through media and didactic exhibitions and publications, of the different items in our collections.

Meteorites are the most unique objects in an Earth science museum, as they are fragments of any solid mass, larger than a molecule and smaller than an asteroid, moving through outer space, which fall onto the Earth's surface. . In other words, they are visitors to the space that we are pleased to host in our scientific collections.
In addition to the unusual genesis of these 'stones' that fall from the sky, they are essential items for understanding the origin and history of planet Earth and our Solar system.
The Earth Science Museum has a tradition in meteorite conservation and research dating back to the early 20th century, with studies carried out by the first directors of the Geological and Mineralogical Service of Brazil. Orville A. Derby and Eusébio Paulo de Oliveira who published, in 1931, a list of meteorites from the collections of the National Museum, the Geological Service and the Escola de Minas.
The meteorite collection of the Museum of Earth Sciences has a few dozen specimens found in the national territory and foreign specimens, from countries such as Argentina, Chile, the United States, Mexico, Latvia and Ukraine, just to name a few, thanks to the exchange of our specimens with other institutions that deal with these meteoritic studies. Our largest example is the Crateús meteorite, weighing 27.5 kg, but we also have fragments from Santa Catarina and Bendegó

Labels, tumble books, cards, correspondence, field notebooks, drawings and photographs constitute the associated documentation.
Not to be overlooked, too, is a good amount of old instruments and equipment that demonstrate the manner and quality of work performed for the identification and studies of all these materials.
