Abstract monocotyledons, the Arecaceae shows by far the The present paper deals with a new petrified palm richest fossil record, and there is an extensive stem having root matrix under the organ genus literature available. Though, fossil material often Palamoxylon (Palmoxylon phytelephantoides lacks sufficient diagnostic detail to allow reasonable association with living palm taxa beyond, or even to, sp. nov.) from Deccan Intertrappean Beds of subfamilial level. However, many fossil genera and Umaria, Madhya Pradesh, India with its numerous species have been described. phytogeographical significance. Detailed anatomical Umaria is one of the well-known plant fossil locality investigations suggest its resemblance with the belongs to Deccan Intertrappean beds which have Phytelephantoid palm, Phytelephas Ruiz & Pavon. been dated 65 million years old (Krishnan, Occurrence of fossils of Phytelephas in the Deccan Intertrappean beds of India and their present 1973). Fossils are scattered and widely spread over distribution in South America and Panama has a in a large area of Umaria, Dindori and Mandla phytogeographical significance.
