We were doing some analysis on rock collected in the early 1990s.
This rock is very important scientifically because it contains fossils which are exceptionally well preserved.
The rock is about 430 million years old.
But with a big thing attached.

We had the gills.
We had the eyes.

It's a very long prolongation coming from the posterior part of the body region.
And ostracods, they have an extraordinary sexual apparatus.
The copulatory appendage, the penis of a male ostracod, can be a third of the total volume of the animal.
And not only that, the spermatozoa that ostracods produce are huge.
You can have a one-millimeter ostracod, an adult ostracod, one millimeter, but he produces a sperm 10 millimeters long.
So 10 times the length of its body, one sperm.
