Sylvilagus floridanus
The eastern cottontail is a species of rabbit in the family Leporidae. It is the most widespread and abundant rabbit species in North America, inhabiting a wide range that extends from southern Canada throughout most of the United States and into parts of Mexico, Central America, and the northern regions of South America. Known for its distinctive fluffy white tail, which resembles a cotton ball and gives the species its common name, the eastern cottontail typically inhabits open fields, meadows, and brushy areas where it can easily find cover and food. It is a primarily herbivorous, crepuscular mammal that feeds on grasses, herbs, twigs, and bark, and plays an important role in the ecosystem as prey for a variety of predators including foxes, hawks, and owls. Due to its adaptability to human-altered landscapes such as suburban and agricultural areas, the eastern cottontail has maintained stable population levels and is not considered threatened. It is also well known for its high reproductive rate, with females capable of producing multiple large litters annually, which contributes to its widespread presence.

Time the record covers
At least 762 thousand years on record.
The record covers at least 774 ka to 11.7 ka. No occurrence read is dated outside 2.58 Mya to 0 Mya.
56 occurrences of Sylvilagus floridanus 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
56 occurrences- Pleistocene94%
- Holocene6%
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.
