Während der Zeit des späten Karbon, etwa 300-320 Millionen Jahre vor heute, lag Norddeutschland am Äquator. Dieses führte zu wesentlichen höheren Temperaturen als in unseren Tagen, mit einer tropischen Vegetation. Fossilien der damaligen Sumpfwälder sind unter anderem Farne, Bärlappgewächse und Schachtelhalme. Die daraus entstandenen Steinkohlen sind Grundlage dieses Vortrages, der sich mit den Vorkommen des Piesbergs bei Osnabrück und von Ibbenbüren beschäftigt. An Hand von anschaulichen Bildern werden Klima, Evolution und Ökologie der Pflanzen- und Tierwelt verständlich gemacht.

Im Geowissenschaftlichen Arbeitskreis bietet der Fachbereich Geowissenschaften einmal im Monat interessierten Laien den Zugang zu Geologie, Paläontologie und Mineralogie. Zentrales Element ist jeweils ein allgemeinverständlicher Vortrag.

Eine spannende Reise durch die Urzeit steht im Mittelpunkt dieses Vortrages. Die Referenten sind in ganz Europa auf der Suche nach Millionen Jahre alten Fossilien. An diesem Abend bringen sie eigene aktuelle Funde aus dem Jahr 2007 mit, einige davon werden an die Zuhörer verteilt. Aus der Betrachtung der Exponate stellen sich spannende Fragen: Welche Lebewesen repräsentieren die Fossilien? Wie waren die Lebensgewohnheiten der Tiere und Pflanzen? Von welchen Organismen stammen sie ab? Warum sind viele Arten ausgestorben?

Anfang 2006 wurde in der Weser bei Bremen-Vegesack der Unterkiefer eines Mammuts gefunden, dass „Stinti“ getauft wurde. Wenn eiszeitliche Säugetierknochen trocknen führt der Volumenverlust zu Rissen, eine Konservierung ist unumgänglich. Bei „Stinti“ entschied sich die Geowissenschaftliche Sammlung für eine PEG-Konservierung. PEG wird seit ca. 30 Jahren sehr erfolgreich in der Archäologie zur Konservierung von feuchtem Holz verwendet. Beispielsweise auch für die Bremer Kogge im Deutschen Schifffahrtsmuseum in Bremerhaven. Martin Krogmann wird die Konservierungsmethode genau erläutern und das Ergebnis präsentieren.

Im Geowissenschaftlichen Arbeitskreis bietet der Fachbereich Geowissenschaften einmal im Monat interessierten Laien den Zugang zu Geologie, Paläontologie und Mineralogie. Zentrales Element ist jeweils ein allgemeinverständlicher Vortrag.

Die Geowissenschaftliche Sammlung besitzt besonders
viele Schalen rezenter mariner und terrestrischer
Mollusken. Unter den etlichen tausend Arten reicht das
Spektrum von mehreren Dezimeter großen Schalen von
Meeresschnecken, bis zu mm-großen Landschnecken.
Die Schnecken wurden weltweit gesammelt, viel Material
ist bereits in historischer Zeit durch die
Handelsbeziehungen Bremens zusammen gekommen.
Die Sammlung rezenter Mollusken ist wie die
paläontologische Sammlung nach systematischen
Kriterien gegliedert und wurde in den letzten Jahren neu
geordnet und auf einen modernen Stand gebracht.

Dieser geologische Reisebericht entführt die Zuhörer von
den Gletschern Südnorwegens bis zu den Lofoten- Inseln
im Nordmeer von Nordnorwegen. Im Süden wurden unter
anderem die Swartisen und Folgefonn Gletscher besucht
und Granite und Gneise studiert. Die Oberflächengestalt
Norwegens ist ohne die Rekonstruktion früherer
Eisvorstösse nicht zu erfassen, denn viele der Strukturen
denen man in der Landschaft begegnet, wie Strudellöchern,
Schleifspuren an Felswänden und Moränenzüge, sind auf
Gletscher zurückzuführen. Nur der Vergleich mit heutigen
Gletschern vermag sie zu erklären.
