Mrtoad Posted April 16, 2021 Share Posted April 16, 2021 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! Link to comment Share on other sites More sharing options...
Jeffrey P Posted April 16, 2021 Share Posted April 16, 2021 That appears to be a suggestively shaped indentation. The suburbs of Philadelphia produce Triassic dinosaur and other reptile footprints so I would keep looking. 1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted April 16, 2021 Share Posted April 16, 2021 I agree, this is not an actual dinosaur footprint. 1 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Mrtoad Posted April 16, 2021 Author Share Posted April 16, 2021 Thank you both for your replies. That is quite the coincidence, but it was a lot of fun researching and coming to this conclusion. Link to comment Share on other sites More sharing options...
Rockwood Posted April 16, 2021 Share Posted April 16, 2021 They typically have a less angular appearance. Here is an example from a track site in Connecticut. 1 1 1 Link to comment Share on other sites More sharing options...
