Wukongopterus Lii

The "Dinosaurs of China" exhibition is now open at Wollaton Hall, Nottingham.  This is an exceptional chance to see some of the most important fossil finds from China at first hand.  The most interesting specimen for me was not the immense casts of the large sauropod and raptor dinosaurs, but the last fossil in the display - The pterosaur Wukongopterus lii.

This specimen is held in a glass case with the reflections of the hall showing on any photograph, but visually, the detail of this fine fossil can be seen.

The magic of direct photography brings the full detail of the specimen to view.  Previously I have only seen drawings and press images of this fossil.  To see the complete specimen is stunning.

This is a basal pterosaur from the Daohugou Beds of Liauning Province.  This is the Holotype - IVPP V-15113.  It is one of the earliest forms of its type from the Late Jurassic, showing similarities with other earlier forms like Darwinopterus.

For me, The exhibition was worth seeing for this one specimen.

 Another interesting fossil is that of Yi qu, a modest sized feathered dinosaur with a bird like skeleton and what appears to be a bat like wing.  This unusual anatomical structure poses questions about its lifestyle.

 Of course, the largest specimen is the Mamenchisaurus hochuanensis which is 23m long and mounted upright to enable it to fit into the main hall gallery.  Wow!

The Lapworth Museum of Geology

 I have not had any contact with the Lapworth Museum at Birmingham University Edgbaston Campus since the mid 1980's.  This museum has seen a significant improvement in many respects since then and is well worth a visit. The  University railway station is a short walk away and it can be accessed from Redditch, Birmingham New Street or Litchfield.

 There is a striking life size model of the skeleton of Pteranodon ingens suspended from  the main fossil gallery ceiling.  This gives a good idea of the size of these large Late Cretaceous pterosaurs.

 A cast of the Bonn fossil of Scaphognathus crassidens shows how the Late Jurassic rhamphorhynchoid pterosaurs had sturdy skeletons and well armed jaws.

 By contrast, the lighter and more gracile Pterodactylus antiquus skeleton cast of one of the Munich specimens shows a different type of Late Jurassic pterosaur.  Both of these casts are of exceptional quality, being professionally produced from the original fossils.  Many commercial copies are not nearly so good.
The museum collections are arranged to give a good understanding about the distribution of fossil types across geological time, which is exactly what a university museum collection should do. 

Of course, there are other aspects of the fossil collections here that are just as interesting and amazing as the pterosaur offerings.  Next time I am in Birmingham I shall consider another visit to this fascinating place.

The Biddulph Grange Gardens Pterosaur

On a recent visit to Biddulph Grange Gardens I was looking at the progress in the geology gallery when I spotted a pterosaur skull on a cast of a lithographic limestone slab.  This was a pterosaur fossil that I had not been aware of.  After contacting the grange, I was put in touch with Daniel Atherton, who is part of the restoration project responsible for the refurbishment of the Geological Gallery.  I was invited to inspect the original slab which was recorded as a fish fossil due to the presence of a number of fish remains visible.

Amongst the fish jaws was a skull resembling that of Pterodactylus antiquus.

The skull is very worn and has many damaged and broken bones.  The upper mandible is obscured by the presence of a fish jaw.  The posterior skull is also broken and part of the basal skull is displaced downwards.

On the edge of the slab is what appears to be a wing bone association.  On original inspection I glossed over this part of the slab.  On closer examination, this represents the dorsal spine and sacrum, with caudal vertebrae at one end and a thoraxic vertebra at the other.  Two fish bones are seen to line up with this associated group of pterosaur bones to give the impression of a pterosaur wing.

 

 The fossil is stored away from the public, but a cast of this slab can be seen in the Geology Gallery at Biddulph Grange Gardens, Staffordshire.
This fossil was collected in Victorian times, but there is no record of the source.  It has only recently been found to contain pterosaur material.  More information will follow as it becomes available.

 

Dinosaur Plate

I recently found this plate at the Emma Bridgewater factory shop in Stoke-on-Trent, UK.  It has been decorated using a sponge print method by hand, showing a sauropod dinosaur surrounded by 8 pterosaurs.  On the back rim can be seen a circle of brown trilobites.

This appears to be a one off design as it has not appeared on the factory stock sheets.  There is a decorating studio on the factory premises where children and adults can pay a small fee for the opportunity to decorate their own pottery.  This may be an uncollected piece which has been sold in store.  It may also be a demonstration plate used by staff at the studio.

Apart from the source and the label on the back, I have no other information on this pottery piece.  Having done an Internet search, it is clear that there is a lot of dinosaur and pterosaur stuff out there.  It is quite fun to see what is available.
