Argyromanis

Argyromanis is an extinct species of mammal of unknown affinities that lived in Argentina during the Miocene. It was described by prolific Argentine paleontologist Florentino Ameghino in 1904 on the basis of a single left astragalus that had been unearthed from the Santacrucian sediments of Santa Cruz, Argentina. Ameghino described it as a species of pangolin, even including this in the genus name's root -manis, after Manidae. The species name patagonica is after the fossil's discovery in Patagonia. However, later analyses of the astragalus have been inconclusive and find it to be an indeterminate genus of mammal.

Time the record covers

At most 1.2 million years on record.

The one occurrence read is dated to somewhere between 17.5 Mya and 16.3 Mya, which is a dating window rather than a span.

1 occurrence of Argyromanis on record, most of them in the Miocene. 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.
