Lost River, WV Clinton Group Fossils

[Megalodoodle]

Here are some fossils from Lost River, WV. They were found near the Needmore formation roadside quarry.

These fossils are not from the Needmore formation, instead they are from the Clinton Group.

The Clinton Group, from what I found during my research, is composed of the Keefer and Rose Hill formations.

First up are some brachiopod impressions. What kind of rock is the matrix?

Squiggles. My best guess is they’re some sort of coral.

Squiggles might be burrows,?  Measurements would be helpful,  at the top of Fossil ID you will see @Coco has provided printable paper for scale.

Okay so the largest squiggle measures 3 cm in length and 0.5 cm in width. The smallest measures 1 cm in length and 0.3 cm in width. The entire rock measures 20 cm x 17 cm x 5 cm (length x width x height).

The absence of zooecia might rule out branching bryozoan. Ichnofossil (such as worm burrows) seem to be the most plausible explanation.
