The Central Government approved an ₹87 crore project under the Swadesh Darshan 2.0 scheme to develop India’s first world-class geological museum and interpretation centre in Madhya Pradesh.

About India’s First World-Class Geological Museum 

  • Location: Bhedaghat–Lamhetaghat, Jabalpur district, Madhya Pradesh (famous for its Marble Rocks and dinosaur fossil heritage like the Titanosaurus).

  • Budget: Approved at ₹87 crore by the Central Government under the Swadesh Darshan 2.0 scheme.

  • Timeline: Implemented by the Madhya Pradesh Tourism Board and targeted for completion by February 2028.  

Geological Significance of the Region 

  • The Lamheta Formation is an internationally acclaimed paleontological site where Captain William Sleeman discovered India’s first dinosaur bones in 1828. 

  • The formation preserves world-famous Late Cretaceous dinosaur skeletal remains, nesting sites, fossilized eggs, and diverse prehistoric flora.

Key Features  

  • Galleries: Six thematic galleries featuring over 130 interactive exhibits detailing the origin of Earth and the geological evolution of the Narmada Valley.

  • Tech Integrations: 3D models, digital panels, interactive touch tables, and an immersive theater.  

  • Outdoor Attractions: Titanosaur Square, a dinosaur park, a fossil garden, a geological maze, rock gardens, a tree-top walkway, and nature trails.  

Lamheta Formation vs Deccan Traps

  • Lamheta Formation (Sedimentary): Represents Late Cretaceous fluvial and lacustrine deposits (66–70 Ma) containing world-renowned dinosaur nesting sites, coprolites, and fossilized titanosaurian eggs.

  • Deccan Traps (Igneous): Represents massive flood basalt eruptions across the Cretaceous–Paleogene boundary (65–66 Ma), caused by the Indian plate passing over the Réunion hotspot, directly overlying the Lamheta beds.

  • Geo-Heritage Value: The junction of Lamheta sediments and Deccan basalt in Jabalpur captures one of Earth's greatest biological transition and mass extinction boundaries.

PRACTICE QUESTION

Q. With reference to the Lamheta Formation in India, consider the following statements:

1. It is a sedimentary geological formation predominantly dated to the Late Cretaceous period.

2. The formation is located in the Narmada Valley and is renowned for the discovery of titanosaurian dinosaur fossils.

3. It directly overlies the Deccan Traps basaltic lava flows throughout central India.

Which of the statements given above is/are correct?

(a) 1 and 2 only

(b) 2 and 3 only

(c) 1 and 3 only

(d) 1, 2 and 3

Answer: (a)

Explanation:  

Statement 1 is correct: The Lameta Formation is a well-known sedimentary geological formation in Central India that is predominantly dated to the Maastrichtian age of the Late Cretaceous period (70 to 66 million years ago).

Statement 2 is correct: It is prominently exposed along the Narmada Valley (such as near Jabalpur and Dhar in Madhya Pradesh). The formation is globally renowned for its extraordinary abundance of dinosaur fossils, particularly titanosaurian sauropods and extensive dinosaur nesting sites.  

Statement 3 is incorrect: Stratigraphically, the Lameta Formation is an infratrappean bed, meaning it underlies (is located beneath) the local basal layers of the Deccan Traps basaltic lava flows rather than overlying them.
