During three hectic days from 25 to 27 October 2013 I attended The Munich Show, one of the most important fossil and mineral fairs in the world.

Marienplatz, in the heart of Munich, was home to medieval markets, celebrations, and tournaments in the 12th century.

 

We arrived Munich on 23 October to install the Museum's exhibition at the Mineralientage München (Munich Show), which this year was devoted to gold in celebration of its 50th anniversary. In the case of fossils this translated as golden discoveries in Palaeontology.

 

The Museum contributed by exhibiting some of our most valuable fossils, including the iconic first finding of Tyrannosaurus rex, an incomplete lower jaw with teeth, which is the holotype of Dynamosaurus imperiosus.

Another important fossil from the Museum was Proceratosaurus, a small-sized carnivorous theropod.

As well as fossil vertebrates the show included invertebrates, like this slab of Balanocrinus and Palaeocoma from the David Harvey Collection.

The Museum displayed specimens from 'golden palaeontological sites' like the Burgess Shale and Lyme Regis.

During the three days I visited all the stands concerning fossils in detail and I saw very striking specimens. Some of them were really uncommon and important scientifically. It was possible to see Edicarian fossils from Russia, really nice slabs of a whole colony of crinoids from Holzmaden or medusae from Solnhofen.

On the other hand, this fossil fair has also been a very good place to see fossil fakes or “reconstructed” fossils.

The show also included activities for children, such as interactive workshops like fossil splitting and soapstone carving.

We enjoyed not only the fossils but also a big party to celebrate the Golden Jubilee on 25 October, the first day of the show, with a Bavarian orchestra that was playing while we had our dinner with typical dishes and drink from Munich, like my favourites ones: Spaetzle with cheese and German beer.

September in Paris

Posted by Consuelo Sendino Oct 13, 2013

Paris is nice at any time of the year! This September has been very warm everywhere and especially in Paris. I have had a Leonardo da Vinci mobility grant to visit the Muséum national d'Histoire naturelle (MNHN) to study how they cope with their digitisation plan.

Georges-Louis Leclerc (1707-1788), Comte de Buffon, intendant (director) at the Jardin du Roi (1739-1788), now called the Jardin des Plantes.

 

I was based in the Département Histoire de la Terre, Laboratoire de Paléontologie, and my host has been Dr Didier Merle, curator of fossil molluscs and editor-in-chief of the palaeontological journal Geodiversitas.

My main interest in this visit was to see how they manage the 'Typothèque', a place where type and figured fossils are housed, and how the MNHN publishes its database of these specimens online.

The Typothèque was created by M. Jean Claude Fischer in 1985 in order to keep all the type and figured specimens of fossil invertebrates together in the same room, making them more accessible to the visitors. This is a big advantage compared to other collections in the same department (fossil plants, fossil vertebrates and micropalaeontology) or other departments at the MNHN. It contains important specimens such as those of the d’Orbigny, d’Archiac and Cossman collections.

 

Currently there is a technician, M. Jean-Michel Pacaud, working full time at this Typothèque, maintaining it and recording any new type or figured specimen. More than 90% of the fossil invertebrates have been databased.

 

The database application used at the MNHN is the demonstrator program JACIM, linked to a paleo database supplying data to the website of the MNHN automatically. An xsp (eXtensible Server Pages Processor) is used to make their collection visible on the website.

Curation at the Typothèque involves using different colour labels depending on whether specimens are types (yellow labels) or figured specimens (white ones), making them visible immediately. Specimens are ordered:

 

      • principally by the main invertebrate groups as gastropods, echinoderms, corals, bryozoans, etc
      • secondly by stratigraphy
      • thirdly by geography
      • finally by alphabetical order of the species name

This organisation is really useful as you can find any specimen kept there immediately. Another advantage  is that the MNHN policy does not allow loans of type specimens. Consequently they are always available for visitors.

 

Congratulations to the MNHN for their well thought out and planned in advance Typothèque!

Specimens in the historical collections housed at the Museum's Palaeontology Building are an invaluable resource for historical research and were the founding core of the British Museum and later the Natural History Museum. They mark the progress of early palaeontological exploration and the collections containing fossils were from:

 

  • Hans Sloane (1660‐1753)
  • Carl Dietrich Eberhard König (1774‐1851)
  • Thomas Pennant (1726‐1798)

 

They are not only the core collections in the Department of Earth Sciences today, but also - through Sir Hans Sloane’s specimens - formed the basis of the British Museum and, ultimately, the Natural History Museum. The collection of König (or Koenig), first Keeper of the Department of Natural History and Modern Curiosities, refers to the fossil and mineralogical core collections that he described in his Icones fossilium sectiles (1825). Lastly, there is the Pennant (1726-1798) Collection, which is from the 18th century zoologist, antiquarian and correspondent of Gilbert White, and was donated to the British Museum in 1912 by the Earl of Denbigh. It has more than 1,000 specimens, some of them described in Pennant’s manuscript Reliquiae Diluviannae, or a Catalogue of such bodies as were deposited in the Earth by the Deluge.

These collections contain fossils of multiple groups: bryozoans, molluscs, echinoderms, brachiopods, sponges, corals, arthropods, worms, fishes, reptiles, mammals, plants and artefacts.

 

The curation of the collections has just finished completely thanks to Marta Martin Mendoza and Jane Barnbrook’s help. Marta is performing a 6 month internship sponsored by the Spanish Government and Jane is a volunteer in the Department of Earth Sciences and the best reboxer ever! While Marta has been databasing and registering the specimens, Jane was reboxing all these with new trays and cutting the plastazote foam used for protection and storage to the shape of each fossil.

The fossil information has been uploaded to our Collection Management System (KE EMu) and is now accessible to other researchers from the Museum website. There are more than 1,300 specimens (with over 1,000 from the Pennant Collection).

 

Among these specimens, there are nice bryozoans such as the lectotype and paralectotype of Blumenbachium globosum Koenig, 1825 in the Koenig Collection, and specimens still unpublished of Cupuladria Canu & Bassler, 1919 in the Pennant Collection.
