Epizoans On Nautiloids From The Ordovician Of Sweden


Dromiopsis

Recommended Posts

Hello!

Here are pictures of epizoans on Anthoceras vaginatum and Endoceras sp shells from the lower-middle Ordovician of Sweden.

I think that it could be inarticulated brachiopods from Craniidea family....

does anyone has seen this before?

Thanks in advance

Do you see any whorls at the ends?

I also think you have pictured a crinoid stalk, while also examining a potential small endo or orthoceras piece that I picked up yesterday.

I agree with Tarquin, They are crinoid holdfasts. Maybe the paleoenvironment was too rough to keep the stem sections?

Hello ,

Thanks both for yours answers,

effectively, there's whorls on the biggest and best specimen conserved.

My eyes are focused on the nautiloids when I arrive on sites each time... :drool:

I will take more time next spring to observe the environment around the nautiloids

Thanks again for your help!

I wonder if that Orthocerid limestone would polish up as well as the stuff from Morocco? ^_^:wub:

Hello Dave,

in the harder levels, it's possible to do as the moroccan stuf, thousands of floors all around scandinavia(old swedish kingdom) got polish nautiloids....I have seen a lot in old buildings(Sweden, Norway). Most of recent polish stones come now from the Västergotland region, Kinnekulle;

you still can buy such floor

Nice specimens.

I have thought the same thing. Here are a couple of specimens I found in Sweden earlier this year, one wet, the other dry. I have not polished them but they do look nice when wet.

All the best,

I think they might also be solitary bryozoan colonies
