上渐新世（Chattian，MP 28）火山口湖Envelope的层状沥青沉积物保存了大量的前植物群和湖泊及其周围动物群的化石。利用场发射扫描电镜技术，我们鉴定了全球罕见的新生代有壳变形虫（Amoebozoa：Thecamoeba）与淡水海绵的芽有关的遗迹。这是盾甲藻硅质壳板的首次记录，一种产自恩斯沃思湖的有壳阿米巴虫。间歇性沼泽和/或附近的海岸栖息地的湖泊Encavity的存在进行了讨论。
The laminated, bituminous sediments of the upper Oligocene (Chattian, MP 28) volcanic crater Lake Enspel preserve a large variety of fossils of the former flora and fauna of the lake and its surroundings. By means of FE-SEM techniques, we have identified the remains of globally rare Cenozoic testate amoebae (Amoebozoa: Thecamoeba) associated with gemmules of freshwater sponges. This is the first record of siliceous shell plates ofScutiglyphasp., an euglyphid testate amoebae from Lake Enspel. The existence of an intermittently swampy and/or near shore habitat of Lake Enspel is discussed.
