RARE conlinoceras (previously calycoceras) tarrantense ammonites, aka "woodbine ammonites,” 6 visible complete ammonites and 0.5 partial ammonites on this slab! These collectors' items locally are only found along the border of the upper woodbine formation where it meets the eagle ford formation, a spotty layer that is difficult to find consistently. The particular location where this was found is in Euless, Texas near interstate 360 during highway construction many years ago.

Please review ALL photos!


The largest 2 ammonites are between 5.5” and 6” diameter, with numerous smaller ammonites and oysters visible as well on both sides.


Mercer Brugler of The Fossil Factory discovered and prepared this grouping using professional air tools (scribe and air abrasive).
