    NEW HOLOCENE ICHTHYO-FOSSIL ASSEMBLAGE FROM EXTRUDED LAGOONAL OUTCROPS, CURONIAN SPIT, LITHUANIA
    (2023) Buynevich, I. V.; Pupienis, D.; Bitinas, A.; Davydov, O. V.; Damušytė, A.; Dambrauskienė, K.; Давидов, О. В.
    Fish remains (ichthyo-fossil assemblages) offer important information about past ecosystems and serve as taphonomic indicators of sedimentation and burial history. In recent years, several sets of fish remains have been collected from lagoonal mark outcrops exposed along the shores of the Curonian Lagoon, Lithuania. Unfortunately, due to ongoing erosion, most of the fossiliferous deposits have disappeared in recent years. Here we present new finds of three separate fish bone accumulations from a previously unsampled outcrop. Based on previous data, these (bream-like) fish are likely mid-Holocene in age and have been buried in a thanatocoenosis, as reflected by the grouping and delicate nature of the fossils, especially the scales.

    SPATIAL AND TEMPORAL VARIATIONS IN MAGNETIC SUSCEPTIBILITY OF COASTAL SANDS RESULTING FROM RECENT STORM ACTIVITY, SAAREMAA ISLAND, ESTONIA
    (2023) Buynevich, I. V.; Tõnisson, H.; Kont, A.; Palginõmm, V.; Suursaar, Ü.; Rosentau, A.; Hang, T.; Pupienis, D.; Davydov, O. V.; Давидов, О. В.
    Coastal strandplains on Saaremaa Island, Estonia, contain a rich archive of past events, which are recorded as geomorphic and lithological indicators of reworking (erosional) and depositional (accretionary) phases. This study presents a new dataset of low-field bulk magnetic susceptibility (MS) values from coastal sands as a rapid means of characterizing the ferrimagnetic and paramagnetic fraction in morphosedimentary units related to cyclone Gudrun (January 2005). Combining spatial and temporal patterns in MS (e.g., >600 SI for most peaks) with granulometric and geophysical databases provides the basis for applying similar integrated approach to reconstructing past extreme coastal events.
