Good Morning,

Found this last month in the Jacksonburg Limestone (Middle Ordovician) near Blairstown, NJ. The smallest division in the pictured ruler are 1/32" or 0.8 mm

Thanks!

I'll third it...but I'd call it a conulariid!

After all these years and one can still learn something new. I never noticed the second "i" in conulariid.

Thanks everybody for the confirmation (and the corrected spelling). This was a float sample from the type locality and I'm looking for a sample of upper Jacksonburg Ls as it is reported to have a silicified fauna (maybe even ostracods!). According to an old faunal survey, the conulariids are found in the upper but not lower Jacksonburg hence the need for an id.

Now I'll dissolve the rock (but save the conulariid) and see what I've got.

Nice conulariid! I would love to see pictures of it after you dissolve the rock! Shoot, I would love to see pictures of the process too! Nice find!

It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.

I kinda like "cornulariid" with salt and butter :)

I'm sure I'm guilty of leaving out the other "i" when I write it but it's always where it belongs when I say it.

That's a nice Ordovician conularid! Is it silicified also? I've collected the Ord. all over the place and have never found a nice conularid. :envy:

Thanks everyone. The acid is on its way and I'll post when I get a sample dissolved. Don't know if the conulariid is silicified - haven't checked yet. On another sample (lower Jacksonburg), there are Leperditia ostracods. Need to sacrifice one to see if it is silicified also.

While, they are common from some later periods, Ordovician conlulariids are very rare.

EDIT: Most that I have seen are a couple of cm, at best. what is the size?

I love the sound of that second "i" -- ee id--e,g; bysonychiid
