Laxifenestella

Laxifenestella is an extinct genus of bryozoans of the family Fenestellidae, found from the Devonian period to the Permian 412.3 to 254.0 million years ago. The genus colonies consist of a mesh of mostly straight branches in a fan-like or funnel-like shape. There are several species belonging to the Laxifenestella genus being L. borealis, L. texana, L. contracta, L. exserta, L. firma, L. morozova, L. lahuseni, L. oviferorsa, L. sarytshevae, L. stuchugorensis and L. stuckenbergi. Parent taxon of this genus is Fenestellidae with siste taxons being Alternifenestella, Minilya, Spinofenestella. Fossils of the laxifenestella genus in the permian period are found in Australia, Canada, Iran, Omen, Pakistan, and Russia. Fossils from the Carboniferous period are found in spain with Devonian period fossils being found in the Czech Republic. In total there are 22 fossils belonging to the Laxifenestella genus.

No picture of Laxifenestella was found. Wikipedia, Wikidata and iDigBio were searched and had none. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Laxifenestella, or no answer at all. This entry cannot say which.

36 occurrences of Laxifenestella on record, most of them in the Permian. 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

36 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 28 sites for Laxifenestella, 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.

21 references

Each of the 36 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. 9 further references are not listed. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
