Devon In Celechovice

The location in Celechovice na Hane belongs to the most significant and most fossil-rich paleontological site in the country. The Celechovice Devon, now uncovered in many old and deserted quarries and outcrops between Celechovice na Hane, Kaple and Slatinky, is classified among shallow-water calcite stage of devonu.

The Celechovice devon is ranked to the shallow-water calcite stage type like the Moravian Karst with prevalence of calcite. During the devon period there was a sweeping flooding throughout Moravia where the sea coming from north first flooded the Jeseniky region and middle part of Drahanska vrchovina highland including western part of Prostejov region (location Konicko, around Stinava).

The location is famous mainly for its rich and well-kept remainders of Paleozoic sea fauna which includes representatives of all then existing species. A notable local petrifact is a cone shaped coral that resembles a calceolaria which was equipped with a lid to prevent mud from leaking inside. Trilobites were also atractive part of the local community – e.g. Dechenella rittbergensis and rare Scutellum flabeliferum with frond tail plate.

The cause of exceptional cumulation of Devonian fauna in calcites unparallel anywhere in the Moravian Paleozoic, can be found in very suitable living conditions of the shallow, warm and well-oxygenated tropical sea.

In 1974 two protected areas were founded in this region – Ruzickuv quarry and the western part of State quarry. Even nowadays when you are lucky, you can still find stones with fossilized organisms in both localities. If you manage to find such a fossil while you are visiting, please, enclose a photo to your log. 

Tasks:

1.Take a photo by the entry to the quarry (spoiler1)

2.Take a photo in Ruzickuv quarry with round holes in backround (spoiler2)

Questions (send me via e-mail: geo.max@seznam.cz):

1. Who or what is “devon”?

2. Measure Ruzickuv quarry elevation above sea-level .

3. What is the color of the layers where the biggest amount of fossils can be found?

4. Find out the Latin name of the trilobite that was named after the local field.

5. On the board of No.11 Velky Kosir nature trail, there is a picture of a cone coral. Find out the Latin name of this coral (spoiler3).

The logs which will not comply with the requirements will be deleted.

Celechovicky Devon

Lokalita Celechovice na Hane patri k nejvyznamnejsim a zkamenelinami nejbohatsim paleontologickym lokalitam nasi republiky. Celechovicky devon, odkryty v rade dnes jiz zarostlych a opustenych lomu a vychozu mezi Celechovicemi na Hane, Kapli a Slatinkami, radime k melkovodnimu vapencovemu vyvoji devonu.

Celechovicky devon radime k melkovodnimu vyvoji typu Moravskeho krasu s prevahou vapencu. V obdobi devonu doslo na Morave k rozsahle zaplave, pricemz od severu postupujici more zaplavilo nejprve oblast Jeseniku a stredni casti Drahanske vrchoviny vcetne zapadniho Prostejovska (Konicko, okoli Stinavy).

Lokalita Celechovice na Hane proslula predevsim bohatstvim a velmi dobrym zachovanim pozustatku prvohorni morske fauny, ktera zahrnuje zastupce vsech tehdy existujicich zivocisnych kmenu. Pozoruhodnou zkamenelinou celechovickeho devonu je kornoutovity koral pripominajici pantoflicek, ktery byl proti vnikani kalu opatren vickem. Atraktivni soucasti zdejsiho spolecestva organismu byli i trilobiti, napr.druhy Dechenella rittbergensis a vzacne Scutellum flabeliferum s vejirovitym ocasnim stitem.

Pricinu nezvykleho nahromadeni devonske fauny v celechovickych vapencich, nemajici obdobu v moravskem paleozoiku, je nutne hledat ve velmi priznivych zivotnich podminkach tehdejsiho melkeho, tepleho, dobre prokysliceneho tropickeho more.

V roce 1974 v katastru obce Celechovice na Hane vyhlasena 2 chranena uzemi - Ruzickuv lom a zapadni cast Statniho lomu. V obou lokalitach lze dodnes nalezt pri trose stesti kameny se zkamenelymi organismy. Pokud se Vam pri sve navsteve podari ucinit takovy nalez, prilozte, prosim, foto ke svemu logu.

Pro zalogovani cache musite splnit tyto podminky:

Ke svemu logu prilozte:

1. Foto u vstupu do lomu (spoiler1).
2. Foto v Ruzickove lomu s kulatymi otvory v pozadi (spoiler2).

Na muj e-mail ( geo.max@seznam.cz) mi zaslete odpovedi na otazky:

1. Co nebo kdo to je devon?
2. Zmerte nadmorskou vysku v Ruzickove lomu.
3. Jakou barvou jsou oznaceny vrstvy, ve kterych se naleza nejvetsi mnozstvi zkamenelin?
4. Uvedte latinske jmeno trilobita, ktery byl pojmenovan podle mistniho naleziste.
5. Na tabuli Naucne stezky Velky Kosir c.11 (spoiler3), ktera je venovana Geologii Velkeho Kosire je vyobrazen kornoutovity koral. Uvedte jeho latinske jmeno.

Nemusíte cekat na potvrzení, jen v pripade nespravneho splneni ukolu o mne asi jeste uslysite...
