Near-Surface Imaging (GPR) of Biogenic Structures in Siliciclastic, Carbonate, and Gypsum Dunes
High-resolution geophysical methods, such as ground-penetrating radar (GPR) imaging, are increasingly applied to ichnological research. Large vertebrate and invertebrate burrows and tracks can beExpand

THE WACO MAMMOTH NATIONAL MONUMENT MAY REPRESENT A DIMINISHED WATERING-HOLE SCENARIO BASED ON PRELIMINARY EVIDENCE OF POST-MORTEM SCAVENGING
Abstract: The Waco Mammoth National Monument (WMNM) potentially represents the only recovered Columbian mammoth (Mammuthus columbi) herd to date, but the “herd” interpretation is dependent on theExpand

Trace fossil evidence suggests widespread dwarfism in response to the end-Cretaceous mass extinction: Braggs, Alabama and Brazos River, Texas
As a proxy for the body size of the tracemaker, burrow diameter provides information on fundamental characteristics such as organism biology and behavior. Furthermore, changes in this endobenthicExpand

Terrestrial evidence for the Lilliput effect across the Cretaceous-Paleogene (K-Pg) boundary
Abstract Recent research has demonstrated that the Lilliput effect (reduction of body size in biota associated with the aftermath of mass extinctions) affected all trophic levels in the marine realmExpand

ICHNOLOGICAL EVIDENCE FOR ENDOBENTHIC RESPONSE TO THE K–PG EVENT, NEW JERSEY, U.S.A.
Abstract Degree of bioturbation, Thalassinoides isp. morphology, and diameters were compared across the Cretaceous–Paleogene (K–Pg) boundary interval at three localities along the New Jersey coastalExpand

Morphological characteristics of preparator air-scribe marks: Implications for taphonomic research
Taphonomic analyses of bone-surface modifications can provide key insights into past biotic involvement with animal remains, as well as elucidate the context(s) of other biostratinomic (pre-burial)Expand

Chemical Composition of Thalassinoides Boxwork Across the Marine K–PG Boundary of Central New Jersey, U.S.A.
Thalassinoides isp. burrow networks filled with green to dark bluish-gray glauconite pellets occur in the Cretaceous to Paleogene Hornerstown Formation and in the uppermost 1–2 m of the underlyingExpand
