Caridea
The Caridea, commonly known as caridean shrimp or true shrimp (from Ancient Greek καρίς, καρίδος, are an infraorder of shrimp within the order Decapoda. This infraorder contains all species of true shrimp. They are found widely around the world in both fresh and salt water. Many other animals with similar names – such as the mud shrimp of Axiidea and the boxer shrimp of Stenopodidea – are not true shrimp, but many have evolved features similar to true shrimp.

Time the record covers
At least 239 million years on record.
The record covers at least 239.48 Mya to 129 ka. No occurrence read is dated outside 241.464 Mya to 11.7 ka.
73 occurrences of Caridea on record, most of them in the Early Cretaceous. 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
73 occurrences- Middle Triassic1%
- Late Triassic8%
- Late Jurassic11%
- Early Cretaceous23%
- Late Cretaceous22%
- Eocene23%
- Oligocene3%
- Miocene7%
- Pleistocene1%
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 52 sites for Caridea, 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.
