Lepidogobius lepidus
Lepidogobius lepidus, the bay goby or finescale goby, is a noticeably resilient and adaptable species of goby, native to the Pacific coast of North America from British Columbia, Canada to Baja California, Mexico where it can be found on muddy substrates from the intertidal zone to about 200 metres (660 ft). This species grows to a length of 10 centimetres (3.9 in) TL. This species is the only extant member of its genus. They can flourish in various kinds of habitats, including brackish waters that have fluctuating salinities. The bay goby has a flattened body, and a distinctive head shape which allows it to seamlessly blend into its surroundings. They appear to be light brown to tan in colour with dark spots or markings on its body. This type of goby fish also possesses a fused fin that forms a disc-like suction which aids in their ability to cling to surfaces and not get swept away by currents. These little fish play a crucial role in the food web of their ecosystems as they are both predators of small crustaceans and prey for large fish.

Time the record covers
At least 2.4 million years on record.
The record covers at least 2.58 Mya to 129 ka. No occurrence read is dated outside 3.6 Mya to 11.7 ka.
5 occurrences of Lepidogobius lepidus 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
5 occurrences- Pliocene20%
- Pleistocene80%
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.

The Paleobiology Database records 5 sites for Lepidogobius lepidus, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.
This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.
