Marada arcanum

Marada arcanum is an extinct species of marsupial discovered in 2001 at the Oligocene Hiatus Site at Riversleigh. It is the only member of the genus Marada. It exhibits plesiomorphic and apomorphic features making the determination of its taxonomic placement difficult. It has been placed within its own family, Maradidae. The specimen consists of the right dentary, with the first incisor but missing the crown, the whole of the horizontal ramus with intact premolar three and molars one to four. The posterior is missing the coronoid process, the articular condyle and the angular process.

No picture of Marada arcanum 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 Marada arcanum, or no answer at all. This entry cannot say which.

Time the record covers

At most 4.3 million years on record.

The one occurrence read is dated to somewhere between 27.3 Mya and 23.04 Mya, which is a dating window rather than a span.

1 occurrence of Marada arcanum on record, most of them in the Oligocene. 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

1 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.
