Giant magnetofossils have exceptionally large grain sizes and peculiar morphologies
compared to conventional biogenic magnetite nanoparticles. The origin of these unusual …

Magnetotactic bacteria biomineralize magnetic minerals with precisely controlled size,
morphology, and stoichiometry. These cosmopolitan bacteria are widely observed in aquatic …

Previous workers identified a magnetically anomalous clay layer deposited on the northern
United States Atlantic Coastal Plain during the Paleocene‐Eocene thermal maximum …

Unusually large and enigmatic giant magnetofossils are well-documented in sediments
deposited during and surrounding climatic events such as the Paleocene-Eocene Thermal …

Near-shore marine sediments deposited during the Paleocene–Eocene Thermal Maximum
at Wilson Lake, NJ, contain abundant conventional and giant magnetofossils. We find that …

Magnetofossils are magnetic nanoparticles that represent the fossil remains of
microorganisms that biomineralize magnetic minerals in a genetically controlled manner …

Conventional magnetofossils represent magnetic mineral remains of magnetotactic bacteria.
Giant magnetofossils have no known modern analog. Both conventional and giant …

We build micromagnetic models to investigate the magnetic properties of biogenic magnetite–
a common type of magnetic mineral that is responsible for recording a wide range of …

One of the most significant characteristics of the Anthro-pocene (the present age of geologic
time) is the rate at which humans are perturbing the global carbon cycle. The potency of …

Magnetofossils are nanosized magnetic fossil remnants of magnetotactic bacteria (MTB) that
are widely distributed in marine and freshwater sediments. Past studies have revealed that …
