　　這是一件藝術品層次的菊石標本，可說是又大又圓，以路德維希菊石來說算是相當大又完美的標本。看看這件菊石背面保留的原始樣貌，再對照正面費時費工清好的成果，大師的清修技藝令人讚嘆！這件菊石化石的產地礦區已關閉近二十年，在西元1985年當Andy Cowap 還是青少年的時候所採集的，整顆菊石清理並經過細緻的拋光，展現出內部礦化與縫合線之美。菊石正面的左右側有不同的礦化，右側屬於乳白潤澤的方解石礦化，縫合線完整而清晰；左側雖然是構成母岩的石灰岩填充而成，但其間的縫合線細看卻是透明的方解石礦化，也能呈現清晰的對比。個人相當喜歡的一件菊石標本，擺設於客廳案頭，猶如一輪明月，風格優雅。

賣家的說明：This is one of the finest examples we have seen of a polished Ludwigia from the famous Horn Park Quarry which closed down operations over eighteen years ago. This specimen was collected by Andy Cowap in 1985 as a young teenager. The outer shell has been ground off to a gem smooth finish then, a high polish applied to reveal stunning suture patterns throughout the ammonite. There is a small piece of matrix which the ammonite lies upon which has a cut base for ease of display. Approximately 175 million years old. A rare and unique item.
