The Katian is the second stage of the Upper Ordovician. It is preceded by the Sandbian and succeeded by the Hirnantian stage. The Katian began 453.0 ± 0.7 million years ago and lasted for about 7.8 million years until the beginning of the Hirnantian 445.2 ± 1.4 million years ago.
The name Katian is derived from Katy Lake (Oklahoma, USA).
The GSSP of the Katian stage is the Black Knob Ridge Section in southeastern Oklahoma (USA). It is an outcrop of the Womble Shale and the Bigfork Chert, the latter containing the lower boundary of the Katian. The lower boundary is defined as the first appearance datum of the graptolite species Diplacanthograptus caudatus. This horizon is 4.0 m above the base of the Bigfork Chert.

I should have treated you a bit warmer
Kept you over here in my corner
After all is said and done
You still got me on the run
A bit longer
Every day and night
I wish I had tried
A bit harder
I should try a little bit harder
I should try a little bit harder
Looking back
I could have been smarter
Maybe given time
We could get it together
I've got memories of our time
Playing over in my mind
I cannot forget
I wish I could make it right
Maybe if I could turn back time
We could have made it if I tried
If I tried
I should try a little bit harder
I should try a little bit harder
I couldn't meet with your demands
So much I couldn't understand
All the good things that we had
Slip like water through my hands
Was I blind that I didn't see
That you needed more from me
How much we had to try
We could make it if I try
I should try a little bit harder
I should try a little bit harder
I should try a little bit harder
