Africa-Press – Togo. <\/strong><\/span>Le site pale\u0301ontologique de Managna a e\u0301te\u0301 de\u0301couvert au de\u0301but des anne\u0301es 80, lors d’une mission de prospection du PIRCAOC a\u0300 la recherche des traces du pre\u0301-homme, le \u00abchai\u0302non manquant\u00bb de l’e\u0301volution des hominide\u0301s qui aboutira plus tard a\u0300 la de\u0301couverte de Toumai\u0308 au Tchad.<\/p>\n

C’est dans le bassin de Koum qui s’e\u0301tend le long du Mayo Rey, depuis Tchollire\u0301 jusqu’a\u0300 Mayo Djarendi, sur 80 x 16km, soit environ 1200 km2 qu’ont e\u0301te\u0301 de\u0301couverts les premiers fossiles de verte\u0301bre\u0301s de la re\u0301gion.<\/p>\n

Des fragments de mandibules de spinosaure, et de nombreuses traces de dinosaures ont e\u0301te\u0301 mis a\u0300 jour notamment a\u0300 proximite\u0301 du village de Managna ou\u0300 l’on peut observer l’une des plus grandes dalles a\u0300 empreintes connues au monde a\u0300 ce jour (400 x 50m, plus de 100 traces et une quarantaine de pistes re\u0301pertorie\u0301es).<\/p>\n

L’inte\u0301re\u0302t du bassin de Koum est essentiel pour la compre\u0301hension de l’histoire des dinosaures; en effet les traces, qui sont observables sur 4 niveaux ge\u0301ologiques diffe\u0301rents, prouvent la pre\u0301sence permanente – jusqu’alors conteste\u0301e – des dinosaures en Afrique sur une longue pe\u0301riode.<\/p>\n

Datation:<\/p>\n

Les empreintes que vous pouvez observer a\u0300 Managna sont date\u0301es d’il y a environ 115 a\u0300 130 million d’anne\u0301es (Cre\u0301tace\u0301 infe\u0301rieur), ce qui correspond a\u0300 la pe\u0301riode estime\u0301e de l’ouverture de l’Atlantique Sud (se\u0301paration de l’Afrique et de l’Ame\u0301rique du Sud). Cette datation est renforce\u0301e par l’existence au Nord-Est du Bre\u0301sil de traces similaires de pre\u0301sence de dinosaures (empreintes, fossiles) et d’un profil ge\u0301ologique semblable jusqu’a\u0300 cette e\u0301poque.<\/p>\n

Trois principaux types d’empreintes peuvent e\u0302tre identifie\u0301s a\u0300 Managna, et prudemment associe\u0301s a\u0300 des espe\u0300ces de dinosaures:<\/p>\n

Les plus grandes, environ 45 cm, correspondraient a\u0300 un Theropode (Spinosaure), dinosaure carnivore, bipe\u0300de tridactyle. Plusieurs tailles de ces empreintes peuvent e\u0302tre observe\u0301es, provenant probablement d’individus d’a\u0302ges diffe\u0301rents. Cette espe\u0300ce pourrait avoir atteint 16 a\u0300 18 m de long et pese\u0301 jusqu’a\u0300 10 tonnes. Il s’agit du plus grand pre\u0301dateur connu.<\/p>\n

Les secondes seraient assimilables a\u0300 un Iguanodonte Ornithopode, bipe\u0300de tridactyle, dont la taille pourrait avoir atteint 7 me\u0300tres pour un poids possible d’environ 2 tonnes.<\/p>\n

Les traces rondes correspondraient a\u0300 un Sauropode (Titanosaure), dinosaure herbivore quadrupe\u0300de, les plus grands e\u0302tres vivant que la terre ait porte\u0301s. On pense qu’ils pouvaient atteindre 22 m de long et peser plus de 50 tonnes…<\/p>\n

Comment y aller?<\/p>\n

Le village de Managna se trouve sur la route allant de Tchollire\u0301 a\u0300 Madingring, 7 km apre\u0300s le carrefour de Tam et 8 km avant l’entre\u0301e du Parc National de Boubandjida. Le site pale\u0301ontologique se trouve a\u0300 4 km au Sud du village; il est accessible en ve\u0301hicule. Pour le visiter s’adresser a\u0300 la chefferie du village, sur la placette situe\u0301e a\u0300 droite de la piste en venant de Tchollire\u0301, juste avant le panneau ‘MANAGNA’.<\/p>\n
