Nick Fraser from the National Museum of Scotland has been at VMNH this week looking through the Triassic material from the Solite Quarry, including both unsorted material and previously studied specimens.

While the abdomen is missing, all eight legs are preserved, as are the pedipalps (the leg-like structures beside the head in spiders), shown in the closeup below (not the greatest image in the world, as this was taken by holding my digital camera up to the microscope eyepiece):
