... Rajput and Khan (1984) identified gymnosperm and monocot wood from the Sindh province. De Franceschi et al. (2008) also found some dicotyledonous fossil wood in the lower portions of the Chitarwal Formation, Sulaiman Range, eastern Baluchistan, while fossil woods from the province of Punjab (Pakistan) have also been documented by Soomro et al. (2016a, b;2017). The current work aims to characterize the fossil wood obtained from the Manchar Formation of the Miocene Age at Thano Bula Khan, Sindh (Pakistan). ...
The characterization of petrified wood provides valuable information about paleoclimatology and geological history and helps to reconstruct the past forest flora of different parts of the earth. The present study was undertaken to evaluate the anatomical characteristics of fossil wood of the Miocene age collected from the Manchar Formation exposed at Thano Bula Khan, Sindh, Pakistan. In order to carry out a detailed anatomical investigation, three-dimensional sections were prepared using a petrotome. The microscopic analysis allowed us to study vessel size and arrangement, wood parenchyma, fibers, and xylem rays. Based on the comparison between recent and fossil wood, we concluded that the investigated characters are comparable with those of the genus Atalantia Corrêa of the Rutaceae family. Therefore, it was named as Atalantioxylon thanobolensis sp. nov. with reference to the location of Thano Bula Khan from which the fossil wood was collected.

The lithofacies studies provide key information to interpret the depositional environments of the sedimentary rocks. Here we study the~1055 m thick Manchar Formation with the age of Miocene to Pliocene which is well exposed at Kari Buthi Division, Northern Laki Range, Southern Indus Basin Sindh, Pakistan. We applied grainsize analysis method to obtain statistical parameters, cumulative frequency curves, discriminatory and discriminatory diagrams. We found that the Manchar Formation encompasses six different fluvial depositional environments including coarse-grained flat bedding sandstone to fine, Conglomerate and agglomerate Sandstone facies, coarse grained trough the cross bedded sandstone facies to sufficient, Shale facies, Mudstone facies, and Clay facies. Principally the common sedimentary structures are trough cross bedding and planner lamination in the area. And the results based on bivariate diagrams further confirm the deposition of Manchar Formation through a braided river system.
