A "Palaeopascichnid" describes a multitude of elongate fossils made up of multiple sausage-shaped chambers.
Fossils of Palaeopascichnids consist of an occasionally branching series of globular or elongate chambers.
These fossils started appearing in the Vendian (late Ediacaran) about 580 million years ago.
[1][2] Fossils of Palaeopascichnids are found in East European platform (White Sea,[3] Urals,[4] Moscow syneclise, Podolia,[5] Finnmark[6]), Siberia (Olenyok uplift, Uchur-Maya basin[7]), South China (Lantian[8]), Australia (Flinders Ranges[9]), India (Tethys[10]), Avalonia (Charnwood,[11] Newfoundland[12]), Romania (Histria Formation[13])
Palaeopascichnid fossils are believed to be the first ever macroorganisms that show signs of an agglutinated skeleton.
