Working in Abu Dhabi, conserving the largest fossil specimen ever to have been found in the United Arab Emirates
In late 2002 Nigel Larkin was contacted by the Abu Dhabi Islands Archaeological Survey (ADIAS) for advice on how to excavate a very fragile and friable eight million year old tusk lying within loose sands of the Arabian desert. Over ten feet long, this is the largest fossil ever to have been found in this area of the Middle East - an area stretching from Pakistan in the east to North Africa in the west. This very long, straight tusk belonged to an early elephantid called Stegotetrabelodon syrticus, further remains of which were found nearby.
We provided ADIAS with several pages of detailed advice, including what methods and materials would be useful to employ, and where the materials could be ordered from. Despite the size and fragility of the specimen and the weakness of the surrounding sediment the excavation was a great success:

In February 2003 Nigel was subsequently invited to travel the three and a half thousand miles to Abu Dhabi to conserve this important, fragile, fossil and prepare it for display. During a nine-day visit the permanent wooden support was added to and strengthened, the field jacket was removed, the fragile specimen consolidated, and some damage from the excavation process was repaired. Also, some areas needed modelling work to disguise repairs, and some hollow areas of the tusk needed infilling to make the specimen more robust and less prone to further damage. A secure permanent support was needed under the whole length of the tusk to hold the tusk and matrix in place when being moved, and this was made with a combination of plaster of Paris and Jesmonite resin. This support was then painted with a mixture of clean sand and glue to disguise it as the intention is to display the tusk as if lying in a natural bed of sand. All processes and materials used were fully reversable, and a full conservation report with diagrams and photographs was submitted within days of completing the project.
As this project was finished slightly ahead of schedule, time was also found to repair and prepare the oldest fossil ever found in Kuwait - the toe bone of a Gomphothere, a very early ancestral form of the elephantidae. ADIAS has asked Nigel to return to Abu Dhabi later in 2003 to prepare and conserve more fossils recently excavated in the desert, including the large lower jaw of a Stegotetrabelodon.
Here are some reconstructions to show you what a stegotetrabelodon elephantid might have looked like:
