The present investigation documents and describes the anchor-shaped Ediacaran organisms assigned to Parvancorina (cf. P. minchami) on the sandstone bedding plane of Sonia Formation of Marwar Supergroup in India. This is the first report of Parvancorina organisms from India. Specimens are preserved as small, rounded to ovate, posterior shield-shaped impressions with an anterior-lateral widened portion and a posterior anchor-shaped structure. P. minchami shows both positive and negative relief preservation modes. In Sonia Formation, the recovered P. minchami specimens have been found in size ranges of 1.5 × 1.5 to 3.0 × 3.5 cm² (length × width), suggesting preservation of adult and larger forms.

目前的调查记录并描述了印度马尔瓦尔超群索尼亚组砂岩层理面上属于Parvancorina（参见P. minchami ）的锚形埃迪卡拉生物。这是印度首次报道Parvancorina生物体。标本保存为小型、圆形至卵形、后盾形印模，具有前外侧加宽部分和后锚形结构。P. minchami表现出正浮雕保存模式和负浮雕保存模式。在索尼亚地层中，发现的P. minchami标本尺寸范围为 1.5 × 1.5 至 3.0 × 3.5 cm ²（长 × 宽），表明保存了成虫和更大的形态。
