I'll be heading up north on a big dig at numerous locations. Today I was able to get out to my Amherstburg/Lucas Fms spot with a focus on Lucas Fm. Why? The Lucas is pretty blank, crystalline, or riddled with nothing but Eridophyllum-esque corals and domic stromatoporoids with a dash of tiny rostroconchs or Amphipora brachs. The sandier layers contain rostroconchs and poorly preserved low-spired gastropod steinkerns. My goal was to perform due diligence as I start filling in the chapter in my Devonian trilobite guide on the Lucas.
Well, the Lucas was not lucky today. Instead, I became distracted with some Amherstburg blocs. Not too much to show, but some lichid pieces.
This is the positive and impression of a lichid fragment with the telltale tubercles. The positive side is almost impossible to make out.
Hypostomes. These are all the same size (about 7 mm wide). The one on the left would likely belong to Acanthopyge contusa on account of how the "divots" are spaced apart, whereas the positive and negative specimen on the right looks more a fit for Echinolichas sp. as the divots are closer together. Again, nothing complete (and likely nothing ever will be in this material), but I think I have more Ontario Devonian lichid material than just about anyone!
Nothing all that exciting or new, but a nice send-off before it's 5-10 days up north to dig into some Ordovician and Silurian material. If I can't come back with fossil riches, I'll at least come back with good memories breaking rock with a great field comrade. Until then...
