This document lists the same quotations, but includes the surrounding context (usually just the paragraph in which Patton's quotation occurs).

I do not know when this collection was assembled, but it appears to be around 1994, judging by the date of the most recent source.

The need for enough biological activity to produce the many cubic kilometres of biogenic limestone observed in the rock record is a fundamental problem with "young Earth global flood" claims. He seems satisfied to say inorganic limestones exist, while ignoring their relative rarity or the fact that most limestones in the geologic record simply did not form this way.

You can probably find a quote in the same book that points this out. These are all discussed in more detail in the section, Descriptions of a Young Earth.

— Richard Dawkins, Until recently, vertebrates have been known from rocks no older than the Middle Ordovician (about 450 million years ago) (1, 2).

In 19 the known range of the vertebrates was extended back about 20 million years by discoveries of fish fossils in rocks of latest Early Ordovician and earliest Middle Ordovician age in Spitzbergen (3, 4) and Australia (5).

Before we come to the sort of sudden bursts that they [Eldredge and Gould] had in mind, there are some conceivable meanings of `sudden bursts' that they most definitely did not have in mind.

These must be cleared out of the way because they have been the subject of serious misunderstandings.

Eldredge and Gould certainly would agree that some very important gaps really are due to imperfections in the fossil record. For example the Cambrian strata of rocks, vintage about 600 million years, are the oldest ones in which we find most of the major invertebrate groups.

And we find many of them already in an advanced state of evolution, the very first time they appear.

It is as though they were just planted there, without any evolutionary history.

Needless to say, this appearance of sudden planting has delighted creationists.
