温德米尔水母

温德米尔水母学名Windermeria)又名温德米尔虫,是前分节动物门双侧水母纲底下的一个物种。在最一开始只发现了一个编号为GSC 102373的化石标本,[2][3]在那之后也陆陆续续地发现了其他化石,可能是亲戚关系关系的管水母虫属英语Annulatubus都是在加拿大英属哥伦比亚省塞奎布鲁克河北边的蓝花地层英语Blueflower Formation[4][5][6][7][8][9]伊沃维克虫属英语Ivovicia一样都生活在大约5亿5千万年到5亿4千3百万年[1][10],也都是双侧水母纲底下的物种。[1]温德米尔水母的是以温德米尔湖(Windermere)命名的,因为此物种的化石就是在温德米尔湖发现的。种小名的“aitkeni”是为了感谢詹姆斯·D·艾特肯(James D. Aitken)对蓝花地层的地理贡献。[2]温德米尔水母长1.64公分,宽0.79公分,大致上是椭圆形,且两边大约平行,身体的头尾两端是圆形的。 而且身体有分节,之中会有沟槽。[2]温德米尔水母是生活在浅水里,与其他当地的双侧水母类不一样,且用匍匐的向前移动。[3][4]
