ID Requested for dragonfly fossil

[dmills727]

I bought this Solnhofen fossil at the Denver Mineral, Gem and Fossil Show this year. Each wing is 6cm long and the body, head to tip of abdomen is 8cm long. It did not come with an id but the vendor contacted his person in Germany who said he would call it Stenophlebia amphitrite. However, I'm seeing online an expected wingspan for that species of 170mm, which this one would fall short of (even if it had the left wings!) 

 

This is my first fossil purchase. I was impressed with the threads I read on this forum before going to the show last week and so would also be interested in critique of the fossil itself -- perhaps that needs to be posted though in a different discussion? 

 

Thank you in advance for guidance on id as well as thoughts on the fossil itself.
