Six million years prior to the KT boundary, there were about twenty species of ammonites in the world's oceans.
第三紀界線前600萬年，全球海洋中大約有20種菊石。
Three million years before the KT boundary, there were only fifteen or so
第三紀界線前300萬年則是15種左右，
and one million years prior to the KT boundary we have less than half of what we started out with,
到了第三紀界線前100萬年，只剩下不到最初的一半，
we have less than ten species, so the extinction event has already been going on for millions of years.
也就是不到10種菊石，這種漸漸消失的情況幾百萬年來一直都在持續。
The amazing thing is that we see the same pattern in the fish record,
令人吃驚的是同樣的情況也發生在魚類記錄中，
we see the same pattern in the terrestrial reptile record, we even see the same pattern in the mammal record.
同樣發生在陸生爬行類記錄中，甚至同樣發生在哺乳動物記錄中。
All of these groups were undergoing an extinction event for millions of years
所有這些物種幾百萬年來都在經歷滅絕事件，
and it would be absolutely amazing to me if dinosaurs weren't undergoing the same sort of extinction
如果恐龍沒有經歷同樣的滅絕，我肯定會感到奇怪，
and indeed I think they were undergoing the same sort of long term extinction.
我確實認為它們同樣經歷了這種長期衰亡。
