V. The Geological Position of the Irvine Whale Bed
Transactions of the Geological Society of Glasgow
In this section high tides rise to about bed No. 4. In the 3rd and 4th beds are specimens of Ostrea edulis, Gardium edule, Littorina littorea, Mytilus edulis, Pecten maximus, and Serobieularia piperata, some in good condition; the bivalves often have the hinge ligament attached, though much decayed, but the smaller shells, though often retaining their shape, are all in a soft, pulpy state. In the thick, upper sand-bed no shells are to be seen, having evidently all been dissolved away by the

At Kidsneuk, on the north-east side of the river, the recentlyconstructed Irvine branch of the Caledonian Railway made a long section through part of these beds, and it was interesting to observe how the different layers all dipped regularly at a gentle angle to the north-west. So much was this the case that had the section been one of solid sandstone, instead of loose sand and gravel, with merely a deposition-dip, one would have been very apt to say that here we had a series of sandstones, several hundred feet thick, No. V.-THE GEOLOGICAL POSITION OP THE IRVINE WHALE BED. By JOHN SMITH. With an Illustration [Plate II.]. [Read 9th February, 1893.] SKIRTING the coast of Ayrshire are certain loose deposits of sand and gravel, at some places represented by beds of clay, which are found up to at least 120 feet above sea-level. These are especially well marked in the district between Ardrossan and the Doon, and nowhere better than about Irvine and Kilwinning, where they reach their greatest breadth, stretching about four miles inland from the present coast-line. Some of the best exposures of these beds are to be seen in the lower reaches of the Irvine Water, for a mile below, and two miles above, Irvine Town Bridge.
