Moyerella

Moyerella is an extinct genus of bryozoan of the family Arthrostylidae, known from the Upper Ordovician and Lower Silurian periods. Its colonies are branching or segmented, generally articulated (jointed). Its autozooecia are short tubes that appear triangular in cross section within the endozone, bending abruptly when reaching the exozone. The autozooecial apertures are round and aligned into diagonal rows, and paired heterozooecia occur between the autozooecial apertures.

19 occurrences of Moyerella on record, most of them in the Silurian. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.

When

19 occurrences

These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

The Paleobiology Database records 19 sites for Moyerella, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.

This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.
