Chondrite Typhoid

Typhoid chondrite (Chondrites abdominotyphosa) is a fossil trace of vital activity found in sedimentary rocks. It is a system of thin branched passages with a diameter of 0.5-3 mm.

These passages have ovoid or rounded cross-sections and often branch dichotomously (into two branches). The branches are usually at right angles to the main course. The walls of the passages are smooth, without traces of attachment or granulation.

Typhoid chondrites are found in marine sedimentary strata of different ages - from the Precambrian to the Cenozoic. Typically associated with shallow marine facies.

It is believed that these passages belong to worm-like organisms that lived in soft soils on the seabed. However, the exact systematic position of the creators of chondrites has not yet been established.
