'A lost ocean in India': Indian Ocean’s 1948 anomaly holds clues to Earth’s ancient past

The Indian Ocean’s gravity anomaly, a 1.2-million-square-mile 'gravity hole,' holds clues to Earth's ancient tectonic shifts, revealing remnants of the Tethys Ocean and magma blobs.

Tethys lives! Researchers propose gravity anomaly under Indian Ocean is the ghost of the long-subducted Tethys Ocean. I studied some bivalves native to Tethys and mourn their fossils possibly subducted into the mantle 🫡 https://www.scientificamerican.com/article/giant-gravity-hole-in-the-ocean-may-be-the-ghost-of-an-ancient-sea/

#Triassic Marine Reptile Had Incredibly Long Tail https://www.sci.news/paleontology/honghesaurus-longicaudalis-11551.html Paper: https://www.nature.com/articles/s41598-022-11309-2

#Pachypleurosaurs are known only from the #TethysOcean, and its potential diet may include soft-bodied #invertebrates (e.g., #cephalopods), some #shrimps, and small or juvenile #fishes. In general morphology, the most striking feature of #Honghesaurus longicaudal is its incredibly long tail, which measures 117% of the precaudal length.
