Scriptural geologists (or Mosaic geologists) were a heterogeneous group of writers in the early nineteenth century, who claimed "the primacy of literalistic biblical exegesis" and a short Young Earth time-scale. Their views were marginalised and ignored by the scientific community of their time. They "had much the same relationship to 'philosophical' (or scientific) geologists as their indirect descendants, the twentieth-century creationists." Paul Wood describes them as "mostly Anglican evangelicals" with "no institutional focus and little sense of commonality". They generally lacked any background in geology, and had little influence even in church circles.
