34 is a species with a patchy County distribution and not often recorded on our field trips. On the sea wall, a cock Wheatear was the only other Spring migrant recorded all day. Surprisingly, the Blackwater Estuary produced very few birds, 5 Scaup and a single Red-throated Diver being the only interesting records. Of the wader species, Grey Plover, Turnstone, Oystercatcher and Sanderling were present in good numbers, with rather fewer Curlew, Dunlin, Ringed Plover and Knot. Altogether a total of 46 species were recorded. A little low for the venue, but not surprising in view of the cold weather. Martin Henry Geology Meeting at Folkestone, 17th April, 1983 The morning began wet and only a very small group of enthusiasts met at Brentwood station, despite the offer of free lifts to Folkestone. As we drove through Kent the rain stopped and we spent a pleasant day walking along the shore and digging in the Gault clay. Late in the afternoon we discovered a layer of large ammonites in the cliff and we spent an exciting hour trying to extract them intact although most of them were already broken. We were so engrossed in our discovery that the arrival of the rain had little effect. We returned laden with specimens to clean and examine at home. Below I have printed some of the information sheet that our leader David Turner prepared. Tony Boniface
