Size: about 3 cm
I took the picture around noon, so the bug has a pretty big shadow

Moved from Orizabus.

Orizabus sp.
This is actually one of the Dynastinae: Pentodontini - probably Orizabus sp. [will place there for now], which is similar to our eastern genus Aphonus and differs from the widespread Tomarus [=Bothynus, Ligyrus] by lacking the typical apical pronotal pit [hard to tell in photo].

Any chance of getting better lit photo? or speciman to examine?

Thanks for the help identifying; sorry I don't have a better photo. I took found this bug while on vacation, and did not have time to get a great shot of it.

C'est la vie
Still good to have it here - remarkably few (none till now) of this group being shot - I'm surprised - I have been expecting to see some Tomarus spp.

NM searchable database
the widespread sp. in NM is O. clunalis. A search on the genus shows three spp., two of which are still valid; O. clunalis (=ligyroides) and O. pyriformis.

Not dung beetle
The superfamily is the same, however: Scaraboidea. Dung beetles are fitted with a broad shovel face that lets them dig rapidly to bury their precious finds of excrement before the flies get to it. This is a scarab of some sort that someone may be able to pin down for you.

As to the hour, shadows pretty much disappear at noon. That looks like a four or five o'clock shadow. Maybe six o'clock even.

What was I thinking! Of course shadows disappear at noon. I remembered taking this shot on the way to lunch-- guess it was dinner.
