What convinced me of evolution is that 99% of all animal species to ever walk the earth have disappeared.
What is the direct evidence for this claim?

Hooby - There have been five mass extinctions in the history of life on earth.

250 million years ago a plume of molten basalt gushed up from the earth's core. It erupted in an area now known as the Siberian Traps - back then it was part of the supercontinent Pangaea.
A curtain of lava a mile high and hundreds of miles long lit up the sky. The eruption known as a "flood basalt" went on for more than 900,000 years. The total amount of lava ejected over that period would have been enough to cover the entire globe to a depth of 20 feet
Dust and ash filled the sky blocking out the sun and leading to a volcanic winter. Then as the sky cleared the earth was wrapped by vast quantities of carbon dioxide given off by the burning lava, creating a greenhouse effect. The earth's temperature rose by 5 degrees celsius.
Over the first 40,000 years many land species became extinct.
Next the oceans began to warm up leading to the extinctions of 96% of marine life over less than 10,000 years.
Then came the third phase when methane began to be released from below the ocean adding to the greenhouse effect and lifting the global temperature by a further 5 degrees over the next 40,000 years. What was left of the planet turned to arid desert killing of most the remaining flora and fauna.
Every living thing on earth today is descended from the 4% that survived.
Known as the Permian extinction or sometimes as "The Great Dying" it was one of five mass extinctions in life's turbulent history.
From the perspective of evolution these events are simply part of the story of life's battle for survival. For creationists they pose an impossible dilemma.

A course in marine biology opened my eyes to the evolutionary process.

Here you go Hooby.
Here is a lengthy article packed with evidence and links to further research...
You're welcome

In this tutorial, we'll discuss the following questions:
What are mass extinctions?
How do we detect mass extinctions in the fossil record?
What role do mass extinctions play in evolution?
What are some common misconceptions about mass extinctions?
How do scientists study mass extinctions?
What evidence do scientists use to study mass extinctions?
What causes mass extinctions?
How could volcanic activity cause mass extinctions?
Are we experiencing a mass extinction now?

I make the effort to post a detailed response laying out the details of the Permian Extinction and some moron responds by clicking 'dislike'.
That there tells you all you need to know about creationism.

The problem for the evolutionist claim “of 99 % of all species have gone extinct” is that the estimated number of living species vastly EXCEEDS the number of extant fossil species (by 20 times!).
So evolutionists would have to be employing a considerable amount of assumptions.

Hooby - You asked for evidence. I provided you with a link to an extensive article jam packed with evidence and loads of links to further research.
You can't even be arsed to click on it.
