Ülevaade
Uurimisrühma põhikompetentside hulka kuulub Eesti geoloogilise ehituse, erinevate kivimite, kivististe ja geoloogilise arenguloo põhjalik tundmine. Sellised baasteadmised on vajalikud praktilises geoloogias, kuid uurimisrühma põhiliseks tegevusvaldkonnaks on alusuuringud, enamasti tihedas rahvusvahelises koostöös. Rühma peamisteks uurimissuundadeks on: • paleokeskkonna ja paleokliima modelleerimine kasutades geokeemilisi ja sedimentoloogilisi indikaatoreid, sh süsiniku ja hapniku isotoopkoostist; • paleoelurikkuse dünaamika modelleerimine ja selle seosed kliima ja keskkonnamuutustega; • erinevate organismirühmade evolutsioon ja paleobiogeograafilise leviku analüüs; • mikropaleontoloogia ja kõrglahutusega biostratigraafia; Oluline osa uurimisrühma tegevusest baseerub instituudi geoloogilistel teaduskollektsioonidel, mis on unikaalseks arhiiviks planeedi kauge mineviku uurimisel. Selle arhiivi haldamist, arendust ja teadlastele avamist korraldab uurimisrühm riikliku teadustaristu programmi ning rahvusvaheliste koostööprojektide raames.

Tähtsamad tulemused
2023. aastal algas uurimisrühmal uus teadusprojekt „Kasvuhoonekliimast jääaega“, mille eesmärgiks on selgitada, kuidas toimus Ordoviitsiumi ajastul (443-487 mln a tagasi) üleminek kuumast kasvuhoonekliimast jääaega ja kuidas see mõjutas elurikkuse dünaamikat Baltika paleokontinendil. Ürgse ookeanivee temperatuuri rekonstrueerimiseks rakendati apatiidi hapnikuisotoopide paleotermomeetrit. Esialgsed tulemused näitasid taksonoomia ja ökoloogia mõju sellele meetodile, kuid kinnitasid üldist kliima jahenemise trendi.
