A new fossil mackerel shark, Pseudocorax kindlimanni sp. nov. (Lamniformes, Pseudocoracidae), is described from the Cenomanian Konservat-Lagerstätte of Haqel, Lebanon. The new species is based on the most complete fossil of this group to date, which comprises an associated tooth set of 70 teeth, six articulated vertebral centra, numerous placoid scales and pieces of unidentifiable mineralized cartilage. The dentition of P. kindlimanni sp. nov. is marked by a high degree of monognathic heterodonty but does not exhibit the characteristic “lamnoid tooth pattern” known from other macrophagous lamniform sharks. In addition, P. kindlimanni sp. nov. shows differences in tooth microstructure and vertebral centrum morphology compared to other lamniform sharks. These variations, however, are also known from other members of this order and do not warrant the assignment of Pseudocorax outside the lamniform sharks. The new fossil is the oldest known pseudocoracid shark and pushes the origin of this group back into the Cenomanian, a time when lamniform sharks underwent a major diversification. This radiation resulted not only in high species diversity, but also in the development of a diverse array of morphological traits and adaptation to different ecological niches. Pseudocorax kindlimanni sp. nov. was a small, active predator capable of fast swimming, and it occupied the lower trophic levels of the marine food web in the Late Cretaceous.

一种新的鲭鲨化石，Pseudocorax kindlimanni sp。十一月 （Lamniformes，Pseudocoracidae），描述自黎巴嫩 Haqel 的 Cenomanian Konservat-Lagerstätte。这个新物种是基于迄今为止该组中最完整的化石，其中包括一组由 70 颗牙齿组成的相关牙齿、六个关节椎体中央、大量的鳞片和无法识别的矿化软骨碎片。P. kindlimanni sp.的牙列。十一月 以高度单颌异齿为特征，但没有表现出其他巨食性lamniform鲨鱼已知的特征性“lamnoid牙齿模式”。此外，P. kindlimannisp。十一月 显示了与其他lamniform鲨鱼相比，牙齿微观结构和椎体形态的差异。然而，这些变异也从该命令的其他成员中得知，并且不保证将Pseudocorax分配到 lamniform 鲨鱼之外。新化石是已知最古老的假珊瑚鲨，并将这一群体的起源推回了 Cenomanian，当时 lamniform 鲨鱼经历了重大的多样化。这种辐射不仅导致了高度的物种多样性，而且还导致了多种形态特征的发展和对不同生态位的适应。假螳螂sp。十一月 是一种能够快速游泳的小型、活跃的捕食者，在白垩纪晚期占据了海洋食物网的较低营养级。
