Zuma, the pictures came from lithiccastinglab and arrowheadology. I wish I could personally find some, but that option is out of my league right now.
There are certainly a lot of very large Daltons being shown, and I don't trust them all, that's for sure. The only ones I trust are from the caches found in Missouri. The picture below is the cache of 13 points from Scott County, MO. The first two pictures above (in reply #1134) are from that cache.

Texas has Daltons and similar types like Golondrina and Barber. They are generally smaller than the Missouri types. I don't have many pictures of Texas Daltons that I trust but there's a couple under the cache picture.
