GARY GAULIN'S DINOSAUR TRACKSITE
What exactly is the above track? One thing is for certain, it does not match the common Grallator tracks found all over Gary Gaulin's tracksite. Scientists that have visited the site are also confused, and believe that this track either represents Eubrontes or Anchisauripus.
You may know about Eubrontes if you visited the Dinosaur State Park Eubrontes page. You may also recognize the name Anchisauripus if you visited the Dinosaur State Park Grallator page. This Grallator page tells a bit about the possible relationship between Grallator and Anchisauripus. Here is a quote taken from that page:
"Often found with Grallator are prints named Anchisauripus ('Anchisaurus foot'), first described by Richard Swann Lull in 1904 as the probable track of the prosauropod dinosaur Anchisaurus ('near reptile'). Specialists now believe that Anchisauripus tracks were made not by a prosauropod but by a theropod, as were those of Grallator. Indeed, it is probable that Anchisauripus tracks-15 to 25 centimeters (6 to 10 inches) long-are the footprints of large individuals of the Grallator trackmaker. The digital formula of the tracks of Grallator, large or small, is (always) ?-3-4-5?."
Is it possible that this track does represent Anchisauripus, and that there is a reason that it was discovered near so many Grallator tracks? Could it be that the above quote is correct, and that Anchisauripus actually represents a larger individual of the Grallator stock? Could Anchisauripus be an adult Grallator?
All of these questions are intriguing, but it is very unlikely that Gaulin's tracksite will give us any new information on the above riddle. Only a select few Anchisauripus tracks are found at Gaulin's site, in relation to the hundreds of Grallator prints. If Anchisauripus indeed was a larger Grallator, the ratio of large individuals to small individuals must have been extremely small (as evident by the small number of the 'large' Anchisauripus tracks and a large number of the 'small' Grallator tracks). But, would there really have been that small of a ratio in the early Jurassic New England ecosystem? This remains unlikely, and because of that fact it is also unlikely that Gaulin's site will provide any answers to the Grallator/Anchisauripus riddle.
