Conodonta
Searched as Conodonta indet.. The Paleobiology Database treats Conodonta as the accepted name.
Conodonts are an extinct group of marine jawless vertebrates belonging to the class Conodonta. They are primarily known from their hard, mineralised tooth-like structures called "conodont elements" that in life were present in the oral cavity and used to process food. Rare soft tissue remains suggest that they had elongate eel-like bodies with large eyes. Conodonts were a long-lasting group with over 300 million years of existence from the Cambrian to the beginning of the Jurassic. Conodont elements are highly distinctive to particular species and are widely used in biostratigraphy as indicative of particular periods of geological time.

Time the record covers
At least 300 million years on record.
The record covers at least 499.5 Mya to 199.5 Mya. No occurrence read is dated outside 504.5 Mya to 184.2 Mya.
313 occurrences of Conodonta on record, most of them in the Ordovician. 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.

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 at least 469 sites for Conodonta, and this reads 240 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.
