While it's basically certain as can be that anthracite is fossilized plants, on account of the leaf imprints, locations, and so on, the evidence for oil is far less conclusive. At the end of the day though it makes no difference. Whether or not the Earth's oil reserves are buried sunshine, primordial hydrocarbons with biological contamination, or both doesn't make much difference. More isn't getting made on human timescales.

False. The paper on which this article is based directly addresses that: Marine sediments produced the majority (about 86%) of the world’s petroleum, while deltaic and lacustrine sediments yielded smaller amounts (about 11% and 3%, respectively) (Demaison, 1993). The organic matter in carbon-rich marine sediments is primarily composed of the remains of phytoplankton. The percentage of annually fixed organic carbon that accumulates in sediment (the PF) is difficult to estimate because it can vary over several orders of magnitude, depending on the length of time that organic matter experiences oxic conditions, and on other factors (Bralower and Thierstein, 1987; Bordenave, 1993; Canfield, 1994; Gélinas et al., 2001). Two types of marine settings are thought to have been the major environments for the formation of petroleum source rocks: silled basins with oxygen-deficient waters, and highly productive upwelling zones (which generated 78% and 8% of world petroleum stocks, respectively; Demaison, 1993). https://www-legacy.dge.carnegiescience.edu/DGE/Dukes/Dukes_ClimChange1.pdf https://www-legacy.dge.carnegiescience.edu/DGE/Dukes/Dukes_C...
