Martes是分布最广的属之一，在现存的食肉动物中可能具有最长的进化历史，但其化石记录并不完整，特别是那些与Martes冠群相关的化石。这里我们描述了一个化石物种，Martes crassidens sp.11月来自辽宁省东北部大连市普湾经济区骆驼山金源洞的中国。这些物质发现于早更新世早-中更新世早期的下部沉积中。我们的形态比较、形态计量学和形态类型分析表明，该化石物种在牙齿健壮、P4原锥扩大和M1内叶方面与全北极貂(这里指HMG)具有明显的亲缘关系，即Martes martes、Martes zibelina、Martes Melampus和Martes americana。它还具有独特的特征，如相对较大的身体尺寸，非常健壮的肉质，高冠M1和相对较短的塔龙鱼，这不同于任何现存的和已知的化石物种，可能暗示了一种食性较强的食性行为。Martes crassidens代表了迄今为止关于HMG的最早记录，并为皇冠貂多样化的年代学框架提供了证据。
Martes is one of the most widely spread genera and probably has the longest evolutionary history among the living Carnivora, yet its fossil record is incomplete, especially those related to the crown group of Martes. Here we describe a fossil species, Martes crassidens sp. nov. from the Jinyuan Cave, Luotuo Hill, Dalian Puwan Economic Zone, Liaoning Province in northeastern China. The materials were found from the lower deposits belonging to the early-middle Early Pleistocene. Our morphological comparison, morphometric and morphotype analyses suggest the fossil species shows a clear affinity to the Holarctic marten group (here referred to HMG), i.e. Martes martes, Martes zibellina, Martes melampus, Martes americana, in having robust dentition, enlarged P4 protocone and M1 inner lobe. It also has unique characters, e.g. relatively large body size, very robust carnassial, high crowned m1 and relatively short talonid, which is different from any living and known fossil species and probably suggests a durophagous dietary behavior. Martes crassidens represents so far the earliest record of the HMG, and provides evidence for the chronological framework of the crown marten diversification.
