Bentonyx (meaning "Michael J. Bentons' claw") is an extinct genus of rhynchosaur from the middle Triassic epoch of Devon in England. Its fossil, a well preserved skull, BRSUG 27200, was discovered in Otter Sandstone Formation (late Anisian age) and was first assigned to Rhynchosaurus spenceri, that is known from 25 specimens. This species was reassigned to its own genus, Fodonyx, that described by David W. E. Hone and Michael J. Benton in 2008. More recently, this skull was reassigned to this genus by Max C. Langer, Felipe C. Montefeltro, David E. Hone, Robin Whatley and Cesar L. Schultz in 2010 and the type species is Bentonyx sidensis.

Hard to live on one buck a day
We were travellin' in the USA
We were travellin' in the USA
My wife's son was two years of age
We were joining the United States
We were joining the United States
I had to borrow some money from a muddy bloody pig
And never met the man before
He said: "Hi ho kid, if I may have your wife
You can keep the money, even more
And you can sell your son for a damned high price
If you travel on to Mexico
And you can borrow my car, a Mustang 66
With a brand new radio"
Hard to live on one buck a day
We were travellin' in the USA
We were travellin' in the USA
So I went down to the border of Mexico
And made a deal with a mexican cat
He said: "Hi ho kid, if I may have your son
You can keep the money, I'll be glad"
Hard to live on one buck a day
We were travellin' in the USA
We were travellin' in the USA
My wife's son was two years of age
We were joining the United States
