Taxonomy

Metoposaurus maleriensis was coined by Chowdbury (1965) for metoposaurid remains from the Maleri Formation in the Pranhita–Godavari Basin of eastern India.[1] Later, Hunt (1993) transferred the species to the genus Buettneria,[2] which was followed by Sulej (2002).[3]

In a paper published in 2018, Chakravorti and Sengupta concluded that specimens of Metoposaurus maleriensis formed a morphospace and morphotype distinct from metoposaurids found in Laurasia. They erected a new genus, Panthasaurus, for M. maleriensis.[4]

gollark: So it works in about 30ms - perfectly okay - *without* the ts_headline, but takes about 30 seconds *with* it.
gollark: It gives a snippet of the page text basically.
gollark: It looks like it somehow incurs a "bitmap heap scan" and "nested loop" but I have no clue why.
gollark: I don't understand why including `ts_headline(pageText, query, 'MaxFragments=3,MaxWords=60')` suddenly makes Postgres decide to operate about 100 times slower on this.
gollark: You lose ubqoral then.
