Dinosaur Print Id?

Recommended Posts

Will try this again--the picture didn't attach for some reason.

I found this print in the creek near my house (Solebury, PA)

Any ideas? Thanks!

What is the size of this print?

Knowing the size is helpful when narrowing down the ID of footprints.

If it is large (dinner plate sized) it could be Eubrontes, but if it is smaller, it could be Anomoepus, or some similar species.

I think the splay of the toes is too wide for Atreipus or Grallator.

Regards,

That's incredible! Finding a print is on my 'bucket list'. Congratulations.

You are in the Triassic/Jurassic strata there; give us the measurements and we can deduce the ichnospecies.

Here is an excellent paper on the dinosaur tracks from neighboring Montgomery County:

At that size, (5" x 5") I would say most likely it is an Anomoepus sp.

Is there some depth in this print? Is the assessment of a footprint based on coloration differential of the rock or other criteria or characteristics also present?

It seems to be very exciting indeed!

Yes, this fossil has an imprint which is what I first noticed when I pulled it out of the creek.

After letting it dry, the color showed up darker than the rest of the rock.

I believe a foot print can either be depressed or elevated...and the color is not always different from the rock? (I'll let the experts speak to this)

Thanks everyone for the input and great resources--I really appreciate it!
