Short summary
We analyze a complex and branched mineral structure with an obscure origin, considering form, matrix, composition, and context. Comparisons eliminate controlled biominerals. The structure's intricate history suggests microbial influence and alterations, followed by a thermal event. Complex interactions shaped its forms, making origin classification tougher. This study highlights the elaborated nature of dubiofossils, identifying challenges in distinguishing biominerals from abiotic minerals.
