TRILOBITE MASS MORTALITY PLATE Prosymphysurus sp.
A mysterious trilobite species, these small compact creatures are beautifully preserved with their rust-brown coloration, in striking aesthetic contrast to the pale gray Moroccan limestone matrix across which they still seem to be scurrying. The skilled preparator has delineated every ridge and furrow of their heavy exoskeletons, reinvesting with life these strange creatures so abundant throughout the earth 500 million years ago. Despite the large number of trilobites in the fossil record, and the vast number of different species, questions still remain, and the Prosymphysurus genus is one of the least researched of all; yet here they are, a tantalizing glimpse into the ancient history of the Earth's fauna. This plate contains over 70 mostly complete examples, ranging in length from 1½ to 2 inches, and the matrix itself measures 33¾ x 17¾ inches.Shipping:

Heritage usually auctions material at the rate of 100-110 lots per hour. On some occasions eBay Live bid software or the Internet may not be able to keep up with the pace of the auction. We recommend placing a realistic absentee bid now as insurance to avoid disappointment. Occasionally the auctioneer may eliminate or reject an eBay Live bid, and the auctioneer may also reopen a lot after the close of the eBay live bidding (usually because we missed an audience bid), and may reject your bid even if it shows you as the winning bidder. By bidding via eBay Live, you agree that Heritage may award the lot to another bidder at its sole discretion under the circumstances described above or any other reasonable circumstances. Since eBay bids are not shown to us until we open the lot on the floor, we treat those bids just like floor bids. In most cases the floor responds before the eBay bid is presented to us, due to Internet lag time, so for consistency we have made it a policy that floor bids are always considered first over tie eBay live bids. Also please note that all Heritage lots purchased through eBay Live carry a 22.50% Buyer's Premium with a $9 minimum Buyer's Premium. Please make sure you read the Terms and Conditions before you bid. This lot is being auctioned in conjunction with a live floor auction by Heritage Auctions. All final auction and invoice information will be supplied by Heritage Auctions, and all other information should be considered preliminary. Lot:41313Winning Notification and Billing:
