Moxostoma anisurum

The silver redhorse is a species of freshwater fish endemic to Canada and the United States. It is the longest-lived redhorse known, with a maximum reported age of 41 years. Sometimes called redhorse or sucker for short, it is in the family Catostomidae with other suckers. The species is distributed from Quebec to Alberta and is also in the Mississippi River, St. Lawrence River, Ohio River, and the Great Lakes basins. The current world record is 6.75 kilograms, caught by Chris Stephenson on Pickwick Lake in Alabama, April 1995 and certified by National Freshwater Fishing Hall of Fame. This species is of growing interest to rod-and-line anglers. The long-lived and late-maturing silver redhorse is also a sportfish pursued by kill-and-dump bowfishing, a 21st century unregulated sport that produces tons of wanton waste, and thus management and conservation are in need of updating.

Time the record covers

At most 129 thousand years on record.

Every occurrence read is dated to somewhere between 129 ka and 0 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

2 occurrences of Moxostoma anisurum on record, most of them in the Pleistocene. The Paleobiology Database records this as a living group. 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

2 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.
