Museum Fire

National Museum of Brazil on fire 2018-09-02

Sad news in that the 200 year old National Museum of Brazil caught fire on September 2, 2018. The museum has over 20 million items in its archive including geological and fossil specimens. Hopefully, they had some digital records and images of the important items in the collection. This is the reason I am such a big proponent of digitizing collections in case something like this happens. Unfortunately, this museum suffered from funding issues which appears why they did not have a sprinkler system so I am guessing no budget for digital records either.

Indiana University Science Hall erected 1874 burned down 1883

Locally, Indiana lost quite a large collection of books and specimens in an 1883 fire. Indiana University had a 3 story building burn down due to a lightning strike. The building housed 14,000 volumes and 85,000 specimens in Owen Cabinet (named for geologists Richard and David Dale Owen). Learn more about this fire at this link. Oddly, a partial skeleton of a giant ground sloth Megalonyx jeffersonii survived but where it is today is not known (except for four of its bones ended up in the Indiana State Museum).

Mesosaurus brasiliensis Aquatic Reptile Fossil


The aquatic reptile fossil pictured is a Mesosaurus brasiliensis  found in the Irati Formation of Brazil. It dates back 280 million years ago (Lower Permian Period). The museum display lists this fossil as one that shows the transition of reptiles to a freshwater environment. It also shows that the continents Africa and South America were connected since this creature's fossils are only found in those two places.

The reptile was thought to its narrow teeth rowed mouth was used to catch fish and other small aquatic creatures. It swam though the water using is long tail and paddle shaped limbs.

The fossil was loaned by Robert H. Osher family to the museum for exhibit.

Polished Slabs at Carnegie Museum

To begin 2012, a tack away from fossils will be taken temporarily for some geological eye candy. The Hillman Hall of Minerals of Gems at the Carnegie Museum of Natural History has a beautiful display of illuminated mineral slices. This posting shows just a few so you will need to visit Pittsburgh, Pennsylvania in person to truly appreciate the beauty of these specimens. The first is an agate and amethyst piece from Brazil. Followed by another Brazilian piece of "bullseye" agate.


This next is is of a cross section of fire opal from Mexico.


This multi-shaded purple specimen is a piece of rhodochrosite from Argentina.


The following image is of an agate from Brazil.


This next picture is of a nephrite jade found in New Zealand.



The last image is of liddicoatite from Madagascar.
