Common elements of this diverse fauna occur to within 2.37 m of the Cretaceous-Tertiary (K-T) boundary. The stratigraphically highest fossil\u00a0in\u00a0the study is a partial ceratopsian skeleton 1.77 m below the K-T boundary\u00a0in\u00a0the basal Fort Union\u00a0Formation. All dinosaurs that occur at more than two sites also occur at the highest level that yielded more than 500 specimens (8.40 m below the K-T boundary). The fine-grained uppermost 2 m of the\u00a0Hell\u00a0Creek\u00a0is nearly devoid of all fossils, including taxa known to occur\u00a0in\u00a0the overlying\u00a0formation. The absence of channel deposits\u00a0in\u00a0this part of the\u00a0formation\u00a0may be the reason for the absence of fossil localities. The presence of marine-tolerant taxa suggests that the study area may have been adjacent to a previously unidentified seaway of latest Cretaceous age. Rarefaction analysis indicates no evidence for a decline\u00a0in\u00a0vertebrate\u00a0diversity through the\u00a0formation\u00a0or dinosaurian diversity\u00a0in\u00a0the 3 m below the K-T boundary. Our results are not compatible with gradual\u00a0vertebrate\u00a0extinction at the end of the Cretaceous.", "description": "19 p.", "publisher": { "@type": "Organization", "name": "Geological Society of America" }, "author": [ { "@type": "Person", "name": "Pearson, Dean", "givenName": "Dean", "familyName": "Pearson" }, { "@type": "Person", "name": "Schaeffer, Terry", "givenName": "Terry", "familyName": "Schaeffer" }, { "@type": "Person", "name": "Johnson, Kirk R.", "givenName": "Kirk R.", "familyName": "Johnson" }, { "@type": "Person", "name": "Nichols, Douglas J.", "givenName": "Douglas J.", "familyName": "Nichols" }, { "@type": "Person", "name": "Hunter, John P.", "givenName": "John P.", "familyName": "Hunter" } ], "spatialCoverage": [ { "@type": "Place", "additionalType": "country", "name": "United States", "url": "https://geonames.org/4074035" }, { "@type": "Place", "additionalType": "state", "name": "North Dakota" }, { "@type": "Place", "geo": [ { "@type": "GeoShape", "additionalProperty": { "@type": "PropertyValue", "name": "GeoJSON", "value": { "type": "FeatureCollection", "features": [ { "type": "Feature", "properties": {}, "geometry": { "type": "Polygon", "coordinates": [ [ [ -99.810791015625, 44.04811573082351 ], [ -96.580810546875, 44.04811573082351 ], [ -96.580810546875, 45.920587344733654 ], [ -99.810791015625, 45.920587344733654 ], [ -99.810791015625, 44.04811573082351 ] ] ] } } ] } } }, { "@type": "GeoCoordinates", "latitude": 44.984351537778586, "longitude": -98.19580078125 } ] } ] }, "OpenAlex": { "abstract_inverted_index": { "Field": [ 0 ], "surveys": [ 1 ], "of": [ 2, 19, 43, 54, 63, 124, 131, 145, 151, 161, 166, 183, 224 ], "the": [ 3, 64, 73, 83, 87, 104, 116, 125, 140, 152, 156, 159, 171, 199, 205, 209, 222, 225 ], "Upper": [ 4 ], "Cretaceous": [ 5, 185 ], "Hell": [ 6, 126 ], "Creek": [ 7, 127 ], "Formation": [ 8 ], "in": [ 9, 72, 86, 139, 148, 195, 204 ], "southwestern": [ 10 ], "North": [ 11 ], "Dakota": [ 12 ], "since": [ 13 ], "1986": [ 14 ], "have": [ 15, 175 ], "produced": [ 16 ], "a": [ 17, 76, 179, 193 ], "total": [ 18 ], "10124": [ 20 ], "specimens": [ 21, 112 ], "from": [ 22, 37 ], "42": [ 23 ], "vertebrate": [ 24, 196, 219 ], "microsites": [ 25 ], "and": [ 26, 50 ], "an": [ 27 ], "additional": [ 28 ], "41": [ 29 ], "dinosaur": [ 30 ], "skulls": [ 31, 36 ], "or": [ 32, 35, 201 ], "partial": [ 33, 77 ], "skeletons": [ 34 ], "separate": [ 38 ], "sites": [ 39, 100 ], "representing": [ 40 ], "61": [ 41 ], "taxa": [ 42, 135, 168 ], "vertebrates": [ 44 ], "dominated": [ 45 ], "by": [ 46 ], "fish,": [ 47 ], "dinosaurs,": [ 48 ], "turtles,": [ 49 ], "crocodilians.": [ 51 ], "Common": [ 52 ], "elements": [ 53 ], "this": [ 55, 149 ], "diverse": [ 56 ], "fauna": [ 57 ], "occur": [ 58, 95, 102, 138 ], "to": [ 59, 137, 178 ], "within": [ 60 ], "2.37": [ 61 ], "m": [ 62, 81, 114, 123, 207 ], "Cretaceous-Tertiary": [ 65 ], "(K-T)": [ 66 ], "boundary.": [ 67, 211 ], "The": [ 68, 119, 143, 164 ], "stratigraphically": [ 69 ], "highest": [ 70, 105 ], "fossil": [ 71, 162 ], "study": [ 74, 172 ], "is": [ 75, 128 ], "ceratopsian": [ 78 ], "skeleton": [ 79 ], "1.77": [ 80 ], "below": [ 82, 115, 208 ], "K-T": [ 84, 117, 210 ], "boundary": [ 85 ], "basal": [ 88 ], "Fort": [ 89 ], "Union": [ 90 ], "Formation.": [ 91 ], "All": [ 92 ], "dinosaurs": [ 93 ], "that": [ 94, 107, 170 ], "at": [ 96, 103, 221 ], "more": [ 97, 109 ], "than": [ 98, 110 ], "two": [ 99 ], "also": [ 101 ], "level": [ 106 ], "yielded": [ 108 ], "500": [ 111 ], "(8.40": [ 113 ], "boundary).": [ 118 ], "fine-grained": [ 120 ], "uppermost": [ 121 ], "2": [ 122 ], "nearly": [ 129 ], "devoid": [ 130 ], "all": [ 132 ], "fossils,": [ 133 ], "including": [ 134 ], "known": [ 136 ], "overlying": [ 141 ], "formation.": [ 142 ], "absence": [ 144, 160 ], "channel": [ 146 ], "deposits": [ 147 ], "part": [ 150 ], "formation": [ 153, 200 ], "may": [ 154, 174 ], "be": [ 155 ], "reason": [ 157 ], "for": [ 158, 192 ], "localities.": [ 163 ], "presence": [ 165 ], "marine-tolerant": [ 167 ], "suggests": [ 169 ], "area": [ 173 ], "been": [ 176 ], "adjacent": [ 177 ], "previously": [ 180 ], "unidentified": [ 181 ], "seaway": [ 182 ], "latest": [ 184 ], "age.": [ 186 ], "Rarefaction": [ 187 ], "analysis": [ 188 ], "indicates": [ 189 ], "no": [ 190 ], "evidence": [ 191 ], "decline": [ 194 ], "diversity": [ 197, 203 ], "through": [ 198 ], "dinosaurian": [ 202 ], "3": [ 206 ], "Our": [ 212 ], "results": [ 213 ], "are": [ 214 ], "not": [ 215 ], "compatible": [ 216 ], "with": [ 217 ], "gradual": [ 218 ], "extinction": [ 220 ], "end": [ 223 ], "Cretaceous.": [ 226 ] }, "apc_list": null, "apc_paid": null, "authorships": [ { "author_position": "first", "author": { "id": "https://openalex.org/A5029331928", "display_name": "Dean A.
