    Hi Everyone,

    A friend of mine collected this fossil for me from the Dallas area. Any ideas of the species?

    Would that be Jurassic? For obvious reasons Dactylioceras sp. springs to mind... I do realise that would likely show a bit more incline, right?

    A very small portion to ID, but possibly Allocrioceras from Cenomanian-Coniacian (Late Cretaceous), example here and here

    OK, so would that make it Eagle Ford Shale?

    Yes :smile:

    If it is Allocrioceras, it could be a number of similar forms from the Eagle Ford Group or the underlying Woodbine Fm. :wink:

    I’d see that nice fragment as good encouragement to go back and look for some more complete specimens.

    Thanks for the information. When I am back in Texas I would love to get to that area and do some hunting of my own.
