"Spaghetti" And Concentrically Laminated Stromatoporoids
"Spaghetti" And Concentrically
Laminated Stromatoporoids
| "Spaghetti" stromatoporoids (a
sponge--the whitish strands in the darker matrix) from the Upper
Devonian Lost Burro Formation, Panamint Range. |
| Here is as second variety of stromatoporoid,
a curious form of sponge, commonly seen in the Upper Devonian
Lost Burro Formation of the Death Valley region--the classically
concentrically laminated stromatoporoids that frequently develop
biohermal masses of tangled sponges scores of feet thick. This
chunk was spotted in the Panamint Range. |
