Grallator footprint or coincidence?

Hello, 

the other day I found this on a hiking trail in Wissahickon park in Philadelphia, pa. 
it looks like a footprint, but the age of the Wissahickon formation is Paleozoic, not Mesozoic. The rock is roughly brick shaped, and there are stone structures/ ruins around the park. It may be a possibility that an old structure was built with Triassic rock, which can be found a short drive west.  I am having trouble identifying the type of rock. Is this a Grallator track, or a Grallator shaped coincidence? 
 

thanks!

That appears to be a suggestively shaped indentation. The suburbs of Philadelphia produce Triassic dinosaur and other reptile footprints so I would keep looking.

I agree, this is not an actual dinosaur footprint.

Thank you both for your replies. That is quite the coincidence, but it was a lot of fun researching and coming to this conclusion.

They typically have a less angular appearance.  Here is an example from a track site in Connecticut.
