筛虾科

放射齿目的一科史前节肢动物

筛虾科学名:Tamisiocarididae)是节肢动物恐虾纲放射齿目里的一[1]这一科都是以浮游生物[1][2] 分布在美国澳洲中国寒武纪海洋[1][2][3][4]大多数的标本都只有保存头部的前附肢而已,但有一些有发现眼睛或头部骨片等其他结构。[1][5]

命名

Tamisiocarididae是由此科的模式种筛虾学名来命名的,由拉丁文tamisium”和“caris”,意思为过滤的螃蟹[6]旧称作鲸虾科(Cetiocaridae),由雅各布·温瑟尔(Jakob Vinther)命名,名字是cetus(鲸鱼)和caris(螃蟹)加起来而成[1],但是这违反了国际动物命名规约第29.1和29.3条,认定此名是一个无效的名字,因为科的名字应是由模式属来命名。[7]直到2019年史蒂芬·帕茨艾莉森·C·戴利两人重新发表并更名为筛虾科。[8]

分类

2022年,约瑟夫·莫伊休克(Joseph Moysiuk)和吉恩-贝尔纳·卡隆英语Jean-Bernard Caron(Jean-Bernard Caron)提出的系统发生树里,比较了筛虾科物种的型态与现今的真节肢动物(Euarthropod)关系较近的物种,发现真节肢动物比起其他奇虾还要更为亲近筛虾科,更而提出筛虾科的物种可能是最早的奇虾;并与后来演化成抱怪虫科、奇虾科和赫德虾科的演化支为姊妹群。[9][10]同年,曾唅等人在论文中提到放射齿目有两个分支:一个是赫德虾科,另一个为非赫德虾科(抱怪虫科、奇虾科和筛虾科),分支点为开拓虾属[11]
