Ageleodus

Ageleodus is an extinct genus of cartilaginous fish from the Paleozoic era. It is known from two species, both of which are based upon isolated teeth. A. pectinatus is known from the Carboniferous of Europe and North America. A. altus was described in 2006 from the Carboniferous of Australia. Four teeth from the Tournaisian deposits of Canning Basin probably present another Australian species although their shape is likely caused by physical wear rather than species features. This genus is also known from the Famennian of the Catskill formation at the Red Hill Site in Hyner, Pennsylvania. A study of 382 specimens from the site showed the strong heterodonty of this genus, which varies widely in tooth length and cusp number. This study described them as A. pectinatus, but the paper which described A. altus tentatively labeled them Ageleodus cf. A. altus. While generally considered a chondrichthyan, it has eluded classification into any known order or family.

6 occurrences of Ageleodus on record, most of them in the Carboniferous. 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

6 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.

28 taxa

The Paleobiology Database records 5 sites for Ageleodus, 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.

Entered from

4 references

Each of the 6 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.
