Recovered from fossil-rich shales spanning Utah, Colorado, and Wyoming, this specimen reflects the exceptional preservation conditions of ancient lake environments.\u003c\/p\u003e\n\u003cp data-end=\"976\" data-start=\"540\"\u003eSumacs are shrubs and small trees that today grow between roughly 3 and 33 feet tall. Their leaves are typically arranged in a spiral pattern and are most often pinnately compound, though some related species may display trifoliate or simple leaves. In living relatives, flowers form dense panicles or upright spikes, composed of numerous small blossoms that may be greenish, creamy white, or reddish in color, each bearing five petals.\u003c\/p\u003e\n\u003cp data-end=\"1512\" data-start=\"978\"\u003eFossil evidence from the Green River Formation demonstrates that members of the sumac family (Anacardiaceae) were a significant component of the vegetation surrounding expansive Eocene freshwater lakes. Although the formation is widely celebrated for its iconic fish fossils, it also preserves a diverse array of plants, invertebrates, reptiles, mammals, and even stromatolitic structures. Plant fossils are especially abundant in these finely laminated shales, offering valuable insight into Paleogene forest composition and climate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003chr\u003e\n\u003ch6\u003e\u003cbr\u003e\u003c\/h6\u003e","brand":"GreenInsect26","offers":[{"title":"Default Title","offer_id":52053375811864,"sku":"06MQQ99","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1250\/0441\/files\/5U8A9163_ddbf9dd9-9d5c-4bee-a057-d8bff1a684fb.jpg?v=1778618722","url":"https:\/\/www.fossilageminerals.com\/products\/1-9-detailed-rhus-nigricans-sumac-fossil-plant-leaf-eocene-age-green-river-ut-06mqq99","provider":"Fossil Age Minerals","version":"1.0","type":"link"}
