Anomoiodon

Anomoiodon is an extinct genus of procolophonine procolophonid parareptile from early Triassic deposits of Thuringia, Germany. It is known only from the holotype MB.R.3539B and paratype MB.R.3539A, two articulated, three-dimensionally preserved partial skeletons on one block which represent two individuals. The holotype includes nearly complete skull and lower jaw. The block was collected from the lowest layer of the Chirotherium Sandstone Member of the Solling Formation, dating to the early Olenekian faunal stage of the Early Triassic, about 249-247 million years ago. It was first named by Friedrich von Huene in 1939 and the type species is Anomoiodon liliensterni. Laura K. Säilä, who redescribed Anomoiodon in 2008, found it to be a leptopleuronine using a phylogenetic analysis. The most recent analysis, performed by Ruta et al. (2011) found it to be a procolophonine instead. However, both analyses found that it is most closely related to the Russian procolophonid Kapes.

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

Time the record covers

At most 5.6 million years on record.

Every occurrence read is dated to somewhere between 247 Mya and 241.464 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

3 occurrences of Anomoiodon on record, most of them in the Middle Triassic. 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

3 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 3 sites for Anomoiodon, and this reads all of them. The number is how many of those sites it was catalogued from too.

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.

Each of the 3 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. 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.
