Diptychus kaznakovi

Diptychus is a genus of freshwater ray-finned fish belonging to the family Cyprinidae, the family which includes the carps, barbs and related fishes. This genus is classified within the subfamily Schizopygopsinae, the mountain barbels. The two species in this genus are found in Himalaya and the Tibetan Plateau of China, India, Nepal and Pakistan, ranging west to the Tien Shan Mountains and Central Asia. The type species is the scaly osman, Diptychus maculatus. The name is derived from the Greek word di, meaning "two", and the Greek word ptyx, meaning "fold". Diptychus is up to 70 cm (2.3 ft) in total length.

Time the record covers

At most 118 thousand years on record.

The one occurrence read is dated to somewhere between 129 ka and 11.7 ka, which is a dating window rather than a span.

1 occurrence of Diptychus kaznakovi on record, most of them in the Pleistocene. 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.
